Taxation Law: CLAT PG / AILET PG Study Survival Guide

Dude, need help badly. Struggling with Taxation Law for PG entrances. Been studying since a month, still can't grasp topics. Tried CLAT PG Taxation Law by A K Maini, but too many complex formulas and concepts, my head starts spinning. Found some notes online, but they're incomplete and lack proper references. Anyone has any suggestions? Need book recommendations that are easy to understand, preferably with good explanations and practice questions. Also, are there any study videos or online resources that can help me grasp the subject? I mean, I've tried Taxmann publications and Taxmann videos, but still, feeling confused. Someone please help, yaar.
