1, the teacher sent out an exercise paper with 50 big questions and small questions, scanned the whole paper quickly, screened out topics that he was not particularly familiar with, and screened out topics that had been done n times.

2. For those exercises that you are already familiar with, you can copy the answers from the book or leave them blank.

Many students like the fun of solving difficult problems, so they show the spirit of not dying until they reach the Yellow River. Sometimes it takes a class to solve a difficult problem, and they have a great sense of accomplishment. But solving a problem in one class is really inefficient, and a master learner would never do it.

3. Focus on overcoming unfamiliar questions, and find more similar questions to practice repeatedly, so that you can learn this kind of questions by heart.

4. Find the corresponding knowledge topics in a round of review books and practice 5 courses. Practice the correct answer, and then analyze the wrong answer. If you do something wrong, practice five more. Repeat this way until you get all five channels at once. If you do the right question, you must fully understand it. If you even guess or choose to do it right with a high probability intuition, it is wrong! Why five? Too little can't judge whether you have mastered it, and too much time consumes too much.

5. For students who have three foundations of A, B and C, after completing the first five steps, they feel that they have made progress and start to advance the questions that were not written in the first two sets of papers to the ladder training according to their own situation.
