I think I failed my pre boards 🙏🙏

Idk bro I haven't been to school since the first set of exams but I asked one guy he told I got 18 in chem out of 40 I'm so cooked I'm so scared. In scoring pretty decent in mocks (b/w 150-175) but I'm shit scared of school now. Pls give tips should I just let it be and study for boards after first attempt or do something about it 😭🙏
