Eligibility is that that you should have done a UG course You can easily find the application on BHU's official site , and you will get all the information on the site Definitely you will get reservation benefit if you are from OBC , SC , ST , EWS , PWD , the application fees is less for these in comparison to general candidates For taking admission is Central university like BHU you will have to give CUET exam which is a national level entrance exam , after the results the cut-offs are released Universitywise and for general the cut off is higher , for other categories the cut offs are lower . I feel that the cut offs should be same for each candidate and the admission process should not be lengthy .
