Yes, you can still apply for B.Ed. Many colleges have entrance for B.Ed admissions. For PTET, you must have a teaching experience of 1-2 years through B.Ed or some education Diploma like D.El.Ed, DIET, etc.

No, it's better to take CAT exam only after pursuing your graduation because to get a call from IIM, it's necessary.

Hi, Congratulations, you got a nice percentage. Do visit the concerned website for detailed information. Thanks.

Eligibility for UG course is 12th passed/appearing with 75% aggregate of best four including 85% in English for general category. A general candidate should have Minimum 60% in four subjects (including mathematics), 54% for OBC, and passing marks are required for SC/ST. B.Com is more of accountancy subjects which will need a lot of time as you are from a science background. I suggest you to choose the course wisely.
