Sir, you can plan to pick up Vashist and Saxena book for self study. The most vital aspect which you need to work on is the conceptual understanding of each chapter. Don't lose heart, most CA students find it tough to score exemplary marks in this subject, you are no exception. But the point to gather is to convert this weakness into your strength with adequate focus and practice in this subject, which will aid you in scoring good marks. Hence, keep practising and prepare well for your examination. Best of luck.
