I want to pursue my higher studies at Khalsa College Amritsar. Which course will be best for the commerce stream without maths after 12th so I get wider opportunities nearby it?

You will get opportunities everywhere if you put in your honest effort and dedication to the job.

Before making any decision, do a good research on the courses offered in Khalsa College. Choose the one that interests you. Also stay open to other choices as well. Make sure that the course you choose provides good job opportunities or research opportunities, and then choose accordingly. 

This institute provides admission for most of the courses based on science (non-medical) background. The best courses if you are from the commerce stream are B.Com (Accounting and Finance) or BBA (Bachelor’s of Business Administration)

Both the fields require strong analytical skills , good communication and knowledge in economics to meet the industry demands. Look out for better opportunities in these fields and analyze them before setting up on one. 

You can also pursue something unrelated to what you studied during 12th, like Fashion Designing or Journalism and Mass Communication.
