Well there are plenty of tricks to learn, but the best is:
-take the overview of the course content
-divide the whole syllabus into parts
-create mind map on a big paper or chart (very helpful)
Other tricks:-
*create shortforms like "Helina ki rab se fariyad" -> H Li Na K Rb Cs Fr
{periodic table 1st column}
*Create your own stories (however stupid it sound).
