Hello,

Your marks in class 12 will affect your interviews in top companies like Microsoft and Amazon. These companies have some eligibility criteria depending upon your 10th, 12th and undergraduate marks. 

These companies only allow the candidated who have more then 

• 80% in 10th
• 70% in 12th 
• 6.00 or 7.00+ opga (depends on companies)

But you can still apply for other companies whose eligibility criteria are less than the marks obtained by you.
