Better go for diploma courses.

If MA eco is your goal don't go for B.com(H).
Entrance exams of various universities foe MA.ECO have a lot of math,econometrics,introductory micro and macro economics as well as welfare economics,etc. which are not taught in B.com(H) and B.com programme.
B.com(H) and B.Com programme are accountancy based course with some subjects related to business management or Business studies in layman language.
Hence,If you wanna go for CA/CS/ICWA/MBA/M.COM than B.COM(H) or B.com programme is best.And if you wanna go for MA eco than BA eco hons is better.

Yes math is compulsory in DU for B.com(H) and B.A.Eco(H).But you can go for B.com programme if you don't have math as an elective subject in class11 and 12.

Yes you can. Start visiting the https://Shiksha.com website panel and talk to admission executive. He will guide you in right way. Also start searching for colleges which has acceptance of 44% B.Com in their college.
