hello Aspirant

I hope you are doing good . As per your query , I would like to inform you that if you dont have course duration issue and getting admission into top nits like trichy,suratkal,allahbad then go for bca+mca only . Reason behind is alumni network , placement opportuinites,coding culure , brand value of tier-1 nit is very better than doing mtech from any private university

However , if you  think you can grow well ,study a lot hard ,you have potential to do comptetive coding without any opportunities then offcourse even from private college noone can stop you to grab big placements

Hope you found this answer helpful. Good luck for your future
