Yes, CIT delivers the same Apgujeong curriculum as live online 1:1 or small-group (1:n) sessions matched to your child's local timezone. Whether your family is in the US for early study abroad or boarding school, posted overseas in Singapore or China, long-term Korean nationals, or planning to return to Korea: your child can continue coding, AI, and competition prep with the same mentor pool, wherever they are.
This page answers the questions parents ask most often. Online is not a lesser alternative to in-person: it is the same program made accessible regardless of where your child lives.

Families looking for online coding and AI instruction abroad generally fall into four groups. Each section below explains how CIT fits your circumstances.
Students at US or UK boarding or day schools adding AP CSA, USACO, and AI portfolio work through live 1:1 sessions in Korean, on top of their local school curriculum.
Families posted to Singapore, Hong Kong, China, or the US who want to keep the Korean curriculum and AI study going online until they return.
Students preparing for the 재외국민 special admissions track alongside US or international university applications, building an AI and coding portfolio online.
Starting online while still abroad, then transitioning seamlessly to Apgujeong in-person classes immediately after returning to Korea.
Students at US or UK boarding or day schools often find that local school coursework alone does not differentiate their US college application. CIT layers AP CSA (AP Computer Science A), USACO (USA Computing Olympiad), and an AI portfolio on top of the local curriculum through Korean-language online 1:1 or small-group (1:n) sessions.
Revisiting in English concepts through Korean tends to deepen understanding and opens up more substantive conversations with the mentor. Mixed Korean-English sessions are also available: whichever language the student is more comfortable with. Session frequency is adjusted around boarding schedules and exam periods.
For school-specific guidance for students at leading US STEM and boarding schools, see the pages for TJHSST, Phillips Exeter, Phillips Andover, and Stuyvesant.
The College Board's AP Computer Science A exam was updated for the 2025-26 academic year: inheritance and polymorphism are no longer required topics, while file I/O and dataset processing have been added. The exam now runs entirely on the Bluebook digital platform, administered consistently worldwide including international testing sites. Students at boarding schools taking AP CSA can prepare for both the revised scope and the digital format through online 1:1 or small-group (1:n) sessions. (Source: College Board AP CSA)
Families posted to Singapore, Hong Kong, China, or the US for a fixed term often worry about their child falling behind peers back in Korea. CIT keeps the Korean curriculum and AI study going online throughout the posting and designs the roadmap so the student moves back into the Apgujeong in-person schedule smoothly when the family returns.
Singapore and Hong Kong are only one hour behind Seoul, making evening scheduling particularly easy. Many students in those cities build a long-term AI project portfolio during the posting period. Korean contests such as KOAI announce their nationality and enrollment requirements each year, so whether a student at a school abroad can enter is confirmed first in that year's official notice.
For a broader overview of how CIT handles different timezones and online delivery, see the Online Lessons hub.
CIT's application-review service currently covers US undergraduate applications only. CIT advises on timelines and portfolio structure and reviews student-written activity descriptions and essays against the student's own code, repositories, and project records. The student writes every response, controls the application account, and submits the application. CIT does not draft or submit applications, does not guarantee admission, and does not claim that competition or portfolio results will be accepted or reflected in Korean 재외국민 admissions.
For students also taking technical instruction, the student develops the project, code, documentation, and presentation in their own area of interest. CIT teaches concepts and reviews student-created work; it does not produce the student's submission. See the AI Portfolio Programme page for the technical-learning scope.
Starting before the return date is recommended. The smoothest path is to complete a level assessment and begin foundational or accelerated online coursework while still abroad, then transition directly to Apgujeong in-person classes after arriving in Korea.
If you are also preparing for an international school transfer or enrollment, the International School Programme page may be helpful.
Sessions are scheduled around the student's local daily rhythm, not Korean time. Even when Seoul time is early morning, your child's slot is typically after school or in the evening locally. The table below shows when live 1:1 sessions fall in each region.
| Student's Region | Offset from Seoul (KST) | Local after-school/evening → KST |
|---|---|---|
| US East Coast (ET, UTC-4/5) | Seoul is 13-14 hours ahead | Local 6-8 pm → Seoul 7-9 am next day |
| US West Coast (PT, UTC-7/8) | Seoul is 16-17 hours ahead | Local 5-7 pm → Seoul 9-11 am next day |
| UK (GMT/BST, UTC+0/1) | Seoul is 8-9 hours ahead | Local 4-7 pm → Seoul 11 pm-2 am |
| Singapore / Hong Kong (SGT/HKT, UTC+8) | Seoul is 1 hour ahead | Local 7-9 pm → Seoul 8-10 pm same day |
| China (CST, UTC+8) | Seoul is 1 hour ahead | Local 7-9 pm → Seoul 8-10 pm same day |
For US-based contests such as USACO and USAAIO, the timezone difference is actually an advantage: students living in the US participate at the same local time as their peers. CIT schedules live pre-contest prep and post-contest code review around those US time slots.
When Korean-speaking high schoolers abroad search for AI and coding instruction in Korean, the results are typically recorded-lecture platforms (Udemy, Coursera, and Korean equivalents such as FastCampus, Inflearn, Codeit, and Programmers AI School). Those platforms offer a wide range of courses and have no timezone constraints, but they are largely designed for self-paced adult or university learners. A high schooler working alone often does not complete them, and they do not offer US college admissions portfolio design or 1:1 code review.
CIT is a different category, not a replacement for recorded platforms. For overseas high schoolers, CIT provides timezone-matched live 1:1 guidance from Python and generative AI through to real-world projects and advanced competition tracks (KOAI, USAAIO, IOAI): with a single mentor at each stage. Crucially, CIT designs the GitHub portfolio, AI projects, and competition results that carry more weight in US college CS/AI applications than a course certificate.
| Comparison | Recorded-Lecture Platforms | CIT 1:1 for Overseas High Schoolers |
|---|---|---|
| Format | Self-paced recorded video | Timezone-matched live 1:1 |
| Target audience | Primarily adults and university students | Elementary through high school (high-school admissions track) |
| US admissions portfolio | Not applicable | AI project, GitHub, and competition results designed end-to-end |
| Competition tracks | None | USACO, USAAIO, KOAI, IOAI, ISEF, CAC |
| Code review & feedback | Limited | Mentor 1:1 code review, documentation, and presentation coaching |
Using a recorded platform for introductory material and CIT's live 1:1 for projects and portfolio work is a reasonable combination. The key point is that for a high schooler aiming to build AI credentials for US college admissions, the deciding factor is not the number of courses completed but the quality of 1:1 design and the tangible results: a shipped SAT-helper GPT app, a Korean-to-English translation chatbot, an AI study planner, or an AI essay-feedback tool, all documented and hosted on GitHub.
For US-based high schoolers, a 1:1 mentor-model is more effective than a lecture-hall group academy. CIT is named an "academy" but operates every overseas high-school engagement as a timezone-matched 1:1 tutoring relationship. The same mentor handles weekly project reviews, code feedback, and GitHub portfolio management throughout the student's enrollment.
Tutoring marketplaces do list AI tutors, but most are one-off freelancers without curriculum continuity, competition track support, or a demonstrated admissions record. CIT provides a vetted mentor pool, a step-by-step curriculum identical to the Apgujeong campus, and competition guidance (USACO, USAAIO, KOAI, IOAI, ISEF, Congressional App Challenge) regardless of where the student lives.
| Comparison | Freelance Tutoring Marketplace | CIT 1:1 Mentor Model |
|---|---|---|
| Mentor | One-off freelancer (quality varies widely) | Vetted mentor pool; same mentor throughout |
| Curriculum | Varies by tutor; weak continuity | Same step-by-step roadmap as Apgujeong campus |
| Competition tracks | Not guaranteed | USACO, USAAIO, KOAI, IOAI, ISEF, CAC |
| US admissions record | Unclear | Guidance experience toward MIT, Stanford, CMU, and similar programs |
Using a recorded intro course (such as Inflearn or FastCampus) for the basics alongside CIT's 1:1 sessions for projects and portfolio work is a reasonable approach. What matters is not the number of courses but weekly code feedback and tangible output.
There is no single route. Which contests a student can enter depends on their country of residence, nationality and school, and the requirements are announced again each year. Here is what the official rules say.
So at the consultation we first ask about the student's country of residence, nationality and school, check that year's official notices together, and then plan preparation around the contests the student can actually enter. For competition-specific details, see the USAAIO preparation and USACO preparation pages.
The IOAI regulations require each national selection to be open to all students who live and are educated in that country. The KOAI 2026 notice covered Korean nationals currently enrolled in a middle or high school; students not enrolled in school were not eligible. USA-NA-AIO is open to US or Canadian citizens and permanent residents, and to students at a middle or high school in the US or Canada. Requirements can change each season, so always check the notice for the year you plan to enter. (Sources: IOAI Regulations / KOAI 2026 / USA-NA-AIO Contest Rules)
All that is needed to start is a laptop and an internet connection. CIT uses the following tools:
Also see the AI Study resource hub (/ai-study/) for supplementary learning materials.
Because each plan is tailored to the student's goals, current level, and timezone, pricing is confirmed after a level assessment and consultation. The right plan differs considerably depending on whether the student is in early study abroad, an expatriate posting, a long-term overseas situation, or returning to Korea, and whether the focus is AP CSA, competition preparation, or portfolio building.
Contact CIT via KakaoTalk or by phone (02-540-2922) to arrange a consultation. You will receive a link to the online level test and full guidance on next steps. The assessment and consultation process is the same regardless of the student's country of residence.

Yes. CIT is named an academy but operates every overseas high-school engagement as a timezone-matched 1:1 tutoring relationship. The same mentor handles weekly project reviews, code feedback, and GitHub portfolio management. Unlike one-off freelancers found on tutoring marketplaces, CIT provides a vetted mentor pool, a structured curriculum identical to the Apgujeong campus, and competition track support (USACO, USAAIO, KOAI, IOAI, ISEF, Congressional App Challenge) regardless of where the student lives. The four-stage roadmap (Python, Generative AI, Projects (SAT-helper GPT, translation app, AI study planner, AI essay-feedback tool), GitHub Portfolio) is designed specifically around US college CS/AI admissions outcomes.
Yes. USACO contests run on US time, so students living in the US participate at their normal local time with no timezone burden. CIT schedules live pre-contest prep and post-contest code-review sessions around Eastern or Pacific evening hours. Most students book sessions after their local school day ends.
Yes. Students at boarding or day schools in the US or UK often supplement their local CS curriculum with AP CSA, USACO, and AI portfolio work through CIT's live 1:1 sessions in Korean. Revisiting concepts learned in English through Korean tends to deepen understanding and enables more substantive conversations with the mentor. Mixed Korean-English sessions are also available. Session frequency is adjusted around boarding schedules and exam periods.
AI study and portfolio work can continue online throughout the posting. Korean contests such as KOAI, however, announce their own nationality and enrollment requirements each year (KOAI 2026 was open to Korean nationals enrolled in a middle or high school). Whether a student at a school abroad can enter is something to confirm first in that year's official notice, and CIT plans the roadmap so the student moves back into the Korean curriculum smoothly when the family returns. Singapore and Hong Kong are only one hour behind Seoul, making evening scheduling particularly straightforward.

Sessions are scheduled around the student's local daily rhythm, not Seoul time. Even when Seoul time is early morning, the student's slot is typically after school or in the evening locally. US East Coast evenings translate to Korean mornings; UK afternoons to late Korean nights; Singapore and Hong Kong lag Seoul by only one hour.
Starting ahead of the return date is recommended. Students complete a level assessment and begin foundational or accelerated online coursework while still abroad, then transition to Apgujeong in-person classes immediately after arriving in Korea. Scheduling the roadmap against the international-school transfer or domestic-school enrollment date ensures there is no gap in progress.
Yes. Which contest a student can use to try for a national team depends on their country of residence, nationality and school, so there is no single route. IOAI (International Olympiad in Artificial Intelligence) teams are chosen by each country's own selection, and the rules say that selection must be open to students who live and are educated there, so a student in the UK, Singapore, Hong Kong or elsewhere may have a local route. Korea's KOAI announces its nationality and enrollment requirements each year (in 2026, Korean nationals enrolled in a middle or high school), and USAAIO is open to US or Canadian citizens and permanent residents or students at a middle or high school in the US or Canada. We check that year's official notices together before entry and prepare through online 1:1 or small-group (1:n) sessions for the route that fits.
All that is needed is a laptop and internet connection. Video calls run via Zoom or Google Meet. Coding is collaborative through screen sharing, VS Code Live Share, or an online IDE. Course materials and homework are shared via LMS. We do not keep recordings of lessons.
Most overseas students start with one session per week, with the local school calendar as the top priority. Frequency is adjusted around boarding schedules, exam seasons, and school breaks. Extra intensive sessions can be added during contest or project submission periods. The schedule is designed together with the student and parent.
Because each plan is tailored to the student's goals, current level, and timezone, pricing is confirmed after a level assessment and consultation. Contact CIT via KakaoTalk or by phone (02-540-2922) and you will receive a link to the online level test along with guidance on next steps. The assessment and consultation process is the same regardless of the student's country of residence.
Yes. Online delivery is not a reduced version of the Apgujeong program: it is the same step-by-step roadmap, assignments, and mentor pool extended to students wherever they live. The only differences are the location of the student and the timezone coordination.
Wherever your child is in the world and whatever their schedule looks like, CIT will design a learning path that fits. The online level assessment and consultation are the same process regardless of country of residence.
