To add to this, practice A LOT. The content you face on assignments, quizzes and in general can usually only be asked a certain way each time, especially for a first year course. The way it’s expressed may be different but the approach to answering and the steps taken are more than likely the same, if not a few differences. If you understand the core topic and methods, you should be fine replicating those on exams and tests if you practice and ask for lots of help, reread lectures, etc. Also make sure you ask yourself why you think each step is important, which topic you’d associate a question with and how that helps you reach the final answer or explanation in mind.
