Hi Vikram,

MA Geography is a really good course so the seats are very limited. Therefore you will have to work hard to get admission in DU. First of all you should be thorough with your syllabus that you have learnt in all the six semesters of your graduation course. Now as far as the videos are concerned to revise the subjects then you can go in YouTube and just type the topic you will get the videos or you can study from eig pathshala. For books you can get the R Gupta's books which are the best from Amazon or other sites.

Good luck!
