Accounting is a technical subject. It is logical. It requires reasoning. Almost every sentence is important so avoid passively highlighting your textbook. When reading, maintain concentration.
Active reading helps concentration.
Try to study the optimum length of time for you at each study session. Try to discover reasons for the methods taught. Monitor your learning. First, consolidate and review at the beginning of each study period. Next, read, question your understanding, then make marginal notes of items you want to restudy.
