Teacher Zhang Yu's topic is biased towards calculation ability and problem-solving skills, so if he is a student with poor foundation, his calculation ability is often not very good, let alone problem-solving skills. Students with poor foundation often don't have enough understanding of basic concepts, and their understanding of definitions is often superficial or even superficial, so most people don't recommend Zhang Yu.

Some questions, sometimes students with poor foundation can work out in one afternoon, and sometimes even several times a day are wrong. Such a topic can be said to be useless for students with poor foundation. This kind of topic is suitable for candidates with good foundation to do all the simple questions and then do them when they encounter difficulties.
