Dear Aspirant,

Most of company which is come for placement they set a eligibility criteria to sit for placement and majority of them set minimum marks in 10th and 12th is 60% above so maybe you will not get offer sit in placement but there are so many company who don't consider 10th 12th that much if your Graduation CGPA is above 6.5 . So don't worry so much about your 12th marks but if you are going to join B.tech make you score more CGPA so that will cover your less mark in 12th. So, try to study hard after 10th and try to get more percentage in 12th class and score more CGPA if you want to do an IT job. And focus more on skills.

Hope this helps.

Good Luck
