hello friends!
To clear exam in given time, I have made a strategy which made me successful.

Step 1 : Material collection
I just take a print of syllabus, and from the very first day I started collecting topics from the books. As I got any of the topic I tick out that topic in the syllabus. In this manner I collected all the syllabus within 4-5 days.

Step 2: Understanding and tick imp lines

After that I started reading whole collected material randomly and ticking on them . I donot bound myself to read in an order. So that my interest never came down and within 15- 20 days I could complete my whole syllabus.

Step 3: Picking up important keywords
When I read whole syllabus once I became confident to point out important keywords to remember whole topic in 4-5 points. I just underlined them with a marker. To complete whole course I took 15-20 days.

Step 4: Learning and revising
As I have collected keywords to remember whole topic. It was very easy to learn and revise them. This took only 4-5 days to revise whole course.

In this manner any one can systematize his studies, and can remove burden of his studies.
