Bro this sucks

Abhi abhi pehle preboards huye aur syllabus abhi hi khatam hua maths ka , I thought ki preboards mai better score kar lunga even if some chapters are not properly revised . Had confidence but after the exam all the hopes were shattered...BC jo question aa rahe they wo bhi galat karke aa gaya...my parents are pretty strict about the marks of pre boards...And now thinking all that shit mai thik se baaki subjects pe bhi dhyan nahi de paa raha..Problem marks nahi hai agle preboards Tak toh wo bhi thik hojayenge but mere parents mera jeena mushkil kar denge...pichli bar half yearly mai thode se no Kam aane par khatarnak bawal machaya tha...

Btw just a rant , and please suggest something to convince my parents 🙏🏻
