In a career crisis

I have completed my engineering in electronics and Communication and got a 6.3 CGPA. I had to take a year off while doing my engineering due to health issues. My engineering didn't go that well.

However I do have basic skills in coding, which I acquired at a training centre that assures placement.

I left the training centre recently and I have an opportunity to do Mtech in Computer Science at PES.

Should I take it ? or should I go back to the training centre ?

Please help me out here.
