B.Com

yes dearu can try in MBA

Dear Ankita,
With 71% marks in 12th , B.com Hons in any college of DU is almost not possible reason being cutoffs goes so high even a average college comes with cut offs of 80%+ .but you can still try because if seat remains vacant then cutoffs will go till 13th or 14th and then it may be possible that you can get admission.
But my advise is you should also apply for B.com as well because cut offs of B.Com remains average and then in 2nd year after scoring good if college permits you can switch to B.com Hons.
All the very best

CA requires lot of patience and hardwork as the success rate is merely 3 % every year and thousands of students do it. While one can not map the human potential ever, you can be the best judge as per your capabilities. There is no age bar to pursue it. The best way is to go through the course in details for all the levels and decide.
All the best
