let me tell you it does effect the campus placements as mentioned by others, but if you are talented and hard working enough companies will always make an exception for you.The companies which does not care about the marks sheet and know that one piece of paper does not decide your future are going to call you for interview if your resume speaks loud about you skills and achievements in the tech industry .

I hope you find it helpful

let me know in the comment box if you are having any further doubts

Thanks

Good luck!
