Hello,
You have forgotten to mention the board that you follow. Assuming that you are from the CBSE background, Then I will share with you a link from where you will get sample question papers for all the subjects of class 10th. The article also has written on how you can download the papers. Solve as many papers as possible as this helps you to recollect the formulas, gives you an idea on where you have to improve and will also help you to manage time better.
