exam stress

I have a serious problem. I'm finding it very difficult to study. It's not that I don't understand or I'm not smart, but I can no longer sit in this chair for even half an hour to study. I have two final exams in science and physics in five days, and I can't study or concentrate. If I don't pass these exams, I won't be able to move on to the next grade. I've deleted all my social media accounts—Snapchat, TikTok, Instagram—and I only keep YouTube. So, if anyone has a solution to this problem, please share it with me. I really need to pass these two exams.

My finals are here only 8 days left and I can't study I tried so hard but I just can't I'm supposed to be graduated this term but lol I'm afraid of failing if I didn't catch up in the right time what I'm supposed to do
