Hey!

If you are not so clear with the concepts of science which will come in your final term examination of class tenth, then you can refer to some youtube videos which explain in a simple and detailed manner. You can also practice sample papers and previous year question papers to know the types of questions asked and repeated questions so you can focus on those specifically. You can download the CBSE science sample papers through the link provided below.
