Hey,

70 percentile is quite low score to target good institutions. So if you are willing to take admission in a good college then I think you should give a reattempt as because if your category if you will work hard a little more then you will shine in the paper.

Although if you doesn't feel like giving a reattempt then VITEE us also a good private college to pursue your engineering degree. The placement is average.

See where you stand in your preparation and whether you can invest more time in this and then decide accordingly.

Hope that helps.

All the best.

Thank you.
