Your mom is only trying to help you prepare for your SATs so that you can do your best and get good results. I know it is difficult when you want to be out with your friends but know you have to revise. Spending some time away from your revision is good as if you revise all of the time it is likely that you will forget everything you are learning. However, this does not mean that you do not revise.....You too must set aside time to stay inside and revise for your SATs as they are important. Don't worry too much, just revise and do you best.
