Hello Vinayak,

This will affect only your immediate future. You can still turn your life around. If you work hard enough, 5 years down the line, this will not matter anymore.

So your PCM aggregate comes out to something below 50%.

SRM,VIT etc. ask for a PCM aggregate of 70%+.

Most good colleges ask for a minimum PCM aggregate of 60%.

So obviously, you are not eligible for any good college via merit.

The way I see it, you have two choices before you:

• Get into a college that accepts your marks via merit. In this case, your fee will be less/moderate depending on the college but the exposure and knowledge you gain will also be less. 
  However, you can still study hard, do courses online, do good projects, gain knowledge by yourself and finally get into a good place.

                                                                 OR

• Get into a college like SRM that accepts students who got below the required criteria via management quota. In this case, your fee will be high but the exposure and knowledge you gain will also be higher.
  In this case you have way better chances at success than the one in the previous case. But you will still have to study hard, do courses online, do good projects and gain knowledge by yourself to get into a good place.

If you can afford it, go with the second option, if not, go with first. But wherever you go, work hard now on and turn your life around. The choice is yours.

Good luck on your future endeavours !!!
