How Do Students Deal With Chemistry Exam Pressure And Time Issues

This semester I had long lectures, lab reports, and also helped at home, so I could not focus well on my chemistry revision. As the exam got closer, I even searched pay someone to take my Chemistry exam just to see how students handle such situations. It made me think about better ways to manage time and stay prepared. Has anyone here found simple and practical methods to prepare for chemistry exams when time feels very limited?
