■Recommended study methods

3.After solving one problem, study in special training
(*If there are any questions you skipped, go to Unanswered questions and solve only the questions you skipped.)
4.Solve the problems checked from Starred problems and repeatedly study the problems you are weak at.
5.Choose Weakness questions to overcome the problems you have solved that have many mistakes, and focus on studying weak problems that are difficult to notice.
6.As a finishing touch, use random questions to check for any oversights. Please make sure that you can answer any question correctly.
