Hi. I am from Mauritius and I need your advice. I am doing my BSc Chem and I will be having my exams this week but I haven't yet revise my theory in kinetics and thermodynamics. What's the best way to revise when time is so short ? To revise the theory ? To start doing only questions ? When I read textbooks, I feel lost; it's like it's very complicated. When I do past papers, I take a long time to do the questions because the questions are not direct and easy. Help me please. I have noticed that one can know his theory very well but if he go to take exams WITHOUT doing the questions, he is stucked !
