Whether taking admission to Ambedkar University Delhi will be difficult or not depends on the course you are choosing.
For undergraduate courses in Economics, the required cutoff is about 2% lower as compared to the University of Delhi. It’s better to opt for AUD, rather than off-campus DU colleges.
For a postgraduate in Economics, the examination pattern and the level of examination is similar to JNU. First, you are required to clear the cutoff objective, only then your subjective answers are marked. You will be shortlisted for the interview, only when you clear the overall cutoff.
