CBSE — NO VARIATION IN MARKS EVEN AFTER VERIFICATION FOR CLASS 12TH RESULT

I got only 64, 66, 73, 78 in physics, maths, chemistry, biology.I didn't expect such marks in this subjects so i applied for verification but then to no change in marks.i expected more marks in this subjects.I expected atleast 90% but due to such low marks i am getting only 75%.this is very disappointing for me.12th result has much more importance in our career but after such a horrible result i don't have confidence to continue towards my goal.it is very depressing so PLZ LOOK FORWARD TO THIS AND RECHECK MY PAPER AND INCREASE MY MARKS IN ALL FOUR SUBJECTS.I AM CONFIDENT THAT THERE IS SOME ERROR IN THE CHECKING OF MY PAPER.IT IS MY HUMBLE REQUEST TO CBSE THAT THEY RECHECK THE PAPER.
