———————————————————————————-REVIEW INSTRUCTIONS——————————————————————————————
Thorough review is critical to the learning process and for most people should take a significant amount of time (and effort!) potentially equalling or surpassing the amount of time taken to do the question set.
- Redo questions that you got wrong or struggled on without looking at the answers or explanations. Think. Rethink. Push yourself. Put pen to paper. Don’t review with only your eyes!
- Once you’ve solved or if you aren’t able to solve in about 10 minutes carefully review the explanation. Again, put pen to paper and redo the question using the the explanation as a guide.
This is a crucial part of the preparation so let’s make sure we get it right.
