Hello there,hope you are doing well.No need to worry much.Placements are done on the basis of  test ,PI rounds also.yes I agree to the fact  that cgpa often matters in the time of placement you have two more years in your hand.one possible way left is to study hard and score good marks in order to balance the cpga.

Feel free to ask me in the comment box if you are having any further doubts

hope you find it helpful

Good Luck!
