– Normal and binomial distributions, and conditional probability.

Do 10 questions today. Tomorrow, before you do the next 10, re-do the 3 hardest ones from yesterday. The Questionbank makes this easy because you can print or screenshot the specific problems you failed.

Here is the 3-step strategy I used to push my students past a 6 and into a 7:

Old HL Paper 1 (no calculator) and Paper 2 (calculator) required speed. If you look at a Questionbank problem and have no idea how to start after 20 minutes, stop . Read the first line of the solution, then try again. This builds problem-solving intuition.
