The official 2027 information schedules Round 1 for Friday, February 19, 2027, 12–3 p.m. ET, at students' schools or USAAIO-authorized test sites with onsite proctoring. The currently published format includes noncoding and Google Colab coding tasks; all code runs on CPU, and GPUs are not allowed. Until detailed Round 1 documents are published, CIT stays within those boundaries using eight steps of shortened simulations and review plus a self-administered full mock near the exam.

The international-school route always remains first. CIT Round 1 preparation can be taken in person in Apgujeong or online across South Korea and overseas, but the official competition is onsite and proctored. Online lessons do not create eligibility, replace a test site, or guarantee advancement, awards, or admissions outcomes.

After U2, a student can use the currently published Round 1 format—three hours, CPU-only code, and Google Colab—to allocate time, prioritize tasks, and review student-written code and reasoning.
U2 is a CIT-designed preparation course, not an organizer program. It combines review based on the public syllabus, a cumulative error log, and shortened CPU-only simulations. CIT will realign the scope and process when detailed 2027 Round 1 documents are published.
Completion or concurrent study of F1, F2, and U1, plus the U0 readiness review, are CIT's internal course-placement criteria. They are not organizer eligibility. Actual participation follows the official Contest Rules and organizer confirmation.
These eight steps are adjustable CIT content units, not eight calendar weeks or eight full mock exams. Based on the official syllabus and currently published 2027 Round 1 format, the plan combines shortened simulations (90 minutes to two hours), one-to-one review, weakness work, and one or two recommended self-administered three-hour mocks near the exam.
| Step | CIT practice topic | Review focus |
|---|---|---|
| 1 | Basic coding + ML (Python/NumPy/Pandas/scikit-learn) | Code accuracy, notebook operation |
| 2 | Math foundations focus | Hand-calculation answer format, Colab markdown |
| 3 | ML advanced (ensembles, bias-variance, CV) | scikit-learn use vs. from-scratch judgment |
| 4 | DL basics + PyTorch MLP | PyTorch code accuracy |
| 5 | CNN basics | Conv hand-calculation + PyTorch implementation |
| 6 | Shortened integrated Round 1 simulation 1 | Time allocation and task priority |
| 7 | Shortened integrated Round 1 simulation 2 | Weakness-area focus |
| 8 | Plan a self-administered three-hour mock near the exam | Exam-day process check |
※ Steps are content units and actual time varies by student. CIT recommends about 10 hours, with an approximate range of 6–14 hours. The latest official competition documents always control.
A CIT process that records errors and revision evidence across practice areas based on the public syllabus, then adjusts the review order.
The official 2027 information says all code runs on CPU and GPUs are neither needed nor allowed. CIT practices code within the published constraint without claiming automatic disqualification.
Students organize and review their own code cells, Markdown, and equations in Google Colab under time limits. Forthcoming detailed Round 1 documents will control the submission format.
Across the eight steps, students record performance trends, errors, revision evidence, and remaining limitations from shortened simulations and optional self-administered full mocks.
We accumulate, as best-practice examples, the standard-template-based answer notebooks written under time pressure.
The currently published 2027 Round 1 format describes noncoding and coding tasks, not a portfolio submission. Student-authored error logs and Colab notebooks can document preparation and revision, but they have no fixed admissions value and guarantee no outcome.

U2 is an optional CIT Round 1 preparation course placed after U1. This sequence is not an official organizer prerequisite. For the full CIT track structure, see the USAAIO Prep Curriculum Hub.

F1, F2, and U1 completion and the U0 readiness review are CIT's internal recommendations for course sequencing, not organizer eligibility. Actual eligibility follows the USAAIO Contest Rules for the relevant season.
CIT uses the currently published 2027 Round 1 format and official syllabus to design eight steps of shortened simulations, one-to-one review, and weakness work, followed by one or two recommended self-administered three-hour mocks. Detailed Round 1 documents are still forthcoming, so the latest official instructions control.
The official 2027 information says Round 1 coding tasks use Google Colab, all code runs on CPU, and GPUs are neither needed nor allowed. CIT does not claim automatic disqualification; students practice CPU-compatible code under the currently published constraint.
No. It is CIT's one-to-one recommendation and may vary from about 6 to 14 hours by student. The eight-step plan does not mean eight calendar weeks or eight full mocks; it combines shortened simulations, review, weakness work, and one or two self-administered three-hour mocks near the exam.
A student who officially qualifies through Round 1 may consider the optional CIT U3 preparation course. U3's A1 and A2 expectations are also CIT readiness criteria; official advancement and the Round 2 schedule and venue are controlled by the organizer.
The current 2027 page calls Round 1 open to everyone, while the Contest Rules list U.S. or Canadian citizenship or permanent residence, or full-time middle or high school study in the U.S. or Canada, among the eligibility conditions. Because the public wording needs reconciliation, ask the organizer. The official competition is onsite and proctored; CIT online lessons do not provide eligibility or replace a test site.
We'll design an individualized mock-exam and review schedule in a diagnostic session, matched to your U1 completion status and the time remaining until Round 1.
