The test is divided into 3 sections:
1. R coding.
2. Python coding. This section includes NumPy and scikit questions.
3. Statistics. This section includes T-tests, Anova regression distributions, and chi-square.
Each section has roughly 12 questions. The number of questions and difficulty is not set in advance, the test is adaptive. The more correct answers you give, the more the questions get tougher. The qualification does not depend upon the number of questions solved, rather on the difficulty level you can achive.
