1, campus idiot: This is the official account of WeChat. I tried, and it's free. You can search the topic of online courses in universities, copy the topic you want to search directly into the input box and send it, and it will return the answer. Voice search is also supported, and the accuracy rate is still very high.

2. Smart campus special train: support supernova, learning power, Zhihu, wisdom tree and various professional online courses. This is an old official account of WeChat, and many friends around us are using it to support supernovae, learning power, Zhihu, the tree of wisdom and various professional online courses.

3. University Monk Search: A necessary search tool for online courses for college students. I don't understand why it is called a university monk, not a college student.

College students' homework completion skills:

The teacher will assign some difficult and simple homework. Don't waste time thinking about difficult problems at this time. Choose a simple one to do it yourself first, and then delve into the problem. Generally, teachers will assign homework according to the content of the lecture that day, so the assigned homework will not be too difficult, because teachers don't want students to spend too much time on difficult problems.

Even if you don't make it in the end, don't be afraid of being criticized by the teacher. Generally, the teacher will focus on some difficult homework problems the next day. You need to listen to what the teacher says about this question. If you don't understand, ask the teacher. The teacher won't blame you too much, because not doing homework and not doing homework are two different things.
