This course takes the math derivations and Colab answer format learned in U1 and automates them under time pressure. With biweekly full mock exams matched to the USAAIO Round 1 (3 hours · CPU only · Google Colab) format and 1:1 wrong-answer reviews, it builds stamina, speed, and accuracy. Since writing GPU-dependent code in the CPU-only environment means disqualification, students internalize the same constraints as the real exam in advance.

After completing U2, in the Round 1 format (3 hours · CPU only · Colab) the student can allocate time and strategically secure partial credit, and operate U1's answer templates automatically under pressure.
U2 does not teach new theory. On top of F1·F2·U1, it only adds exam execution skills: through biweekly full mock exams, a cumulative wrong-answer log, and CPU-only environment simulation, it builds real-exam instincts.
F1·F2 + U1 Completion (or concurrent enrollment) is Required, and you U0 eligibility assessment must have passed it. For the full track, see the USAAIO Prep Curriculum Hub reference.
Below is the standard 8-week plan on a 1:1 basis. We mix shortened mocks (90 minutes–2 hours) + 1:1 review + weakness reinforcement, and recommend self-administering a 3-hour full mock (the same duration as the real Round 1) once or twice right before the exam.
| Week | Mock exam 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 | Round 1 integrated simulation 1 | Time allocation, partial-credit strategy |
| 7 | Round 1 integrated simulation 2 | Weakness-area focus |
| 8 | Round 1 integrated simulation 3 (just before the exam) | Exam-day operations manual |
※ Weeks are content units; actual time varies by student. Recommended about 10 hours, ranging 6–14 hours.
A CIT-validated methodology that cumulatively tracks wrong answers across the 7 USAAIO topic areas and automatically generates a spaced-retrieval schedule.
Round 1 uses a Colab CPU-only environment. Since GPU-dependent code means disqualification, we repeatedly train a feel for the model size and complexity that run on CPU.
We automate the LaTeX + code-cell mixed answer template learned in U1 under time pressure to eliminate formatting losses.
We accumulate, as data, the change in mock-exam scores over 8 weeks and wrong answers across the 7 topic areas to quantitatively visualize weak areas.
We accumulate, as best-practice examples, the standard-template-based answer notebooks written under time pressure.
USAAIO is a purely performance-based exam that does not evaluate portfolios. However, a systematic wrong-answer log and standardized Colab answer notebooks serve as admissions material that shows the depth of competition preparation that you can pull from when needed and process all at once.

U2. Round 1 Mock Bootcamp
Round 1 exam-format focus
You must have completed F1·F2 and U1 or be taking them concurrently, and you must have passed the U0 eligibility assessment. This is because U2 does not re-teach ML theory and only trains your ability to run the Round 1 exam.
It covers the entire official scope of USAAIO Round 1 (Markdown·Math foundations·Basic coding·ML·Advanced PyTorch·DL foundation·CNN basics) through 8 weeks of biweekly full mock exams and 1:1 wrong-answer reviews.
Round 1 is taken in a Colab CPU-only environment. Writing GPU-dependent code results in disqualification, so we build, through simulation, an early instinct for the model size and complexity that run on CPU.
No. It's a recommendation on a 1:1 basis and varies by ±30–50% (about 6–14 hours). We mix shortened mocks (90 minutes–2 hours) + 1:1 review + weakness reinforcement, and recommend self-administering a 3-hour full mock once or twice right before the exam.
If you pass Round 1, you continue to U3 (Round 2 Bootcamp). U3 also requires completing A1·A2. Check the USAAIO Competition Guide for the exact schedule.
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.
