Degree

Please do M.Com first, and then B.Ed to become a teacher.

There are immense job opportunities, but the most important thing is your passion/dream/goal. All the best.

I think St. Albert college is more good because of following reasons
Firstly,
The National Assessment and Accreditation Council (NAAC) has accredited the College at the A.
Secondly,
Notable Alumni
Simon Britto Rodrigues
Dominic Presentation
Both of them had paid a prominent role in kerela legislative assembly.
At the end I will say that fees for particular degree should also be checked and if it is affordable college is good.

Screening is based on merit and you have taken two years extra plus your percentage is also not good, hence you might face some issue in the admission, for more details contact the college authorities:

Hello Vaibhav,
I am sure that you are talking about lateral admission after Diploma. Unfortunately such information is not available on internet. But I am sure if you get 75 percentile in Diploma, you would get college of your choice.
