What are some study tips from a Statistics scholarship winner? Part 2 on exam preparation.

(d) Review notes: before each midterm and final exam, I always read the slides and textbook, and make a set of review notes. This includes key concepts, important derivations, and simple examples. I find myself understanding the material much better after writing the important things down neatly. I put more emphasis on things that I am confused about and refer to this set of notes through my exam prep period.
(e) Questions: while I make my review notes, I write down any questions that I come up with beside the corresponding section of the notes. After the notes are completed, I come back to these questions and see if I can answer them having gone through all of the materials covered.
(f) Exam and homework problems: I always keep all of my returned midterms and homework sets. I think it’s important to look back at the problems I have done after a while. For the questions I got wrong, I analyze what caused the mistakes and make sure I understand the concept so that I can avoid making the same mistakes again. For the questions I got right, they can serve as a good refresher to the concepts that might not have been touched on for a while.
