To be honest, my way of getting an A might not be the best way possible but it worked for me as most of the time I study for the exams this way. I always used to start one day before the exam dates and used to allocate around 3 hours for each chapter. Going through the entire chapters from the book is a must if someone wants to do well in the exams and the IOAs are also to be taken very seriously. The IOAs also help to prepare for the exams in advance. The review or the sample questions from the website also helped a lot during the exam. For the presentation and group report, it is essential to take help from Sir during his office hours and use the office hours effectively. Finding fun in the way of education is the only shortcut of achieving success in education.
