        I took the discrete mathematics test today , Choosing to fill in the blank can also be done , But when it comes to proof , Some don't know how to do it , There is a proof that the formula is not remembered , Youdao is very similar to the title of the textbook , I didn't practice before , Later, when reviewing, I just looked , I didn't completely understand how it came from . Although the exam passed , But I don't think I have a good grasp . Then I reviewed the digital circuit and logic design , Did a set of questions , There are still many deficiencies in the design problem . Study , Need to take the initiative , This semester's study is still a little passive , Listen passively , Passive homework , Only review , But I didn't practice , Only practice + Only by summarizing can we master .
