First of all, the final exam results of the university include the usual results and the final exam results. Therefore, the final exam results are very important, and the interaction with teachers is also very important. Talk more in class at ordinary times, finish your homework carefully after class, and ask more questions if you don't understand, which will improve your usual grades and your final grades.

Second, learn from your classmates. They got more than 90 points in the exam. They must have a unique learning method. So you can choose a few classmates with good relationships, exchange ideas, ask their learning methods and learn from them.

The above is based on your question and my experience.

I hope my answer can help you and make you satisfied.

Finally, I wish you a happy new year and progress in your studies.
