MBA or Job in IT ?

Hello everyone , I recently completed my BE in CSE from a tier 3 college and somehow landed a job in TCS which was the hardest part in itself .
I also gave MBA CET ( for Maharashtra ) just for fun in which is scored 87%
Now the thing is for OBC category this can land me a good if not best MBA college to get another degree
But I am very much confused as I didn’t even get joining letter I am just waiting and this score is valid only for this year and Distance MBA is not worth it is what I’ve heard
So what to do should I wait for joining and start working in TCS or should I go for full time MBA ?
Also are there any colleges in Pune which will allow me to do full time MBA while working ?
