Will your performance in class 9th affect your grades in 10th, No. Will the grades of class 9th appear on the report card of class 10th, Yes.
CGPA that you’ll achieve in class 10 will be purely based on your performance in 10th standard only. One of my friends didn’t do that well in 9th but secured an overall CGPA of 10 in class 10th.
So no worries, though study hard in 9
