Questions, answered
Is this official USMLE material?
No. USMLE Radar is an independent study tool. Our questions are original and written for practice, not copied from any exam.
Which exams does it cover?
Step 1, Step 2 CK and Step 3, each with its own schedule and performance view.
How does the schedule personalize itself?
You set your exam date and daily time. After every block we compare your accuracy by topic and move weak areas earlier and more often.
Can I study in Portuguese?
The interface, explanations and analytics switch between English and Português. Questions stay in English because the exam is in English.
Will it predict my score?
It shows a range from your recent performance. Treat it as a compass, not a promise.
Can I use it on my phone?
Yes. Blocks, review and your calendar are built to work with one thumb.
Your first block is ready.
