Which one is better, TAPMI or Fore in Delhi?

It depends entirely on which specialization you want to choose. I know a few people from both TAPMI and FORE. So, I think I can give you some information about these two institutes which may be helpful for choosing which is best for you. 

For Marketing: 

If you want a career in marketing, go for FORE. 

• FORE has better faculty for Marketing specialization. 
• The internship offers they offer are majorly from Sales, Business Development, and Market Research. 
• For placements, many major FMCG companies visit the campus. Profiles mostly offered in placements are Area Sales Manager. 
• The highest salary received here is 30 LPA while the average salary is 10.6 LPA.
• FORE also has the added advantage of being located near the Commercial hub of Gurgaon, Delhi. 

For Finance:

• TAPMI is very good if you want to pursue your career in finance. It has a very good faculty and all the top sector companies visit the campus for placements. 
• The highest package observed here is 25 LPA while the average salary is 11 LPA.

The placement statistics for both these two institutes are authentic and not inflated. Both the colleges are good and have their own advantages.
