Hii aspirant

I prepared for MSc Physics. I prepared with highest dedication for 1 month. I secured an AIR 129, even if I had BSc in Mathematics. 

What I did ? I just did questions. A lot of questions. And if I felt like while doing them, then only I looked at theory. 

You can get some course material from VPM Classes and practice as many questions as possible. I was studying 6+ hours every day for one month, without a single day break. And if I can get a AIR 129 with one month of preparation, and that too being from Mathematics background, you can do wonders in 6 months. 

Consistency is important. Perseverance is important. So you should devote at least 2 hours everyday, NO MATTER WHAT. And more than 3 hours on weekends. That will be enough. Make sure you focus on lot of question.
