I have already attempted to learn the textbook of Biochemistry by heart; however, most information and knowledge contained in it genuinely went away from my mind just after a biochemical exam. Then, I recognize that it is no use trying to keep in mind every reactions or enzymes because the number of them is too large to remember. It is the foremost reason why I only reread Biochemistry when my clinical rotations began. At each time this book is opened, I only focus on chemical factors or processes related to paraclinical tests (like hepatic enzymes, plasma billirubin, creatinin, ure,etc). Thanks to the study procedure, I can now memorize necessary information thoroughly and have no difficulty applying it into clinical situations. Consequently, I find the method quite effective
