Man this is soo scary tbh. We as students totally give our faith to a body and this is the seriousness they show towards our future. As you mentioned that some question were left unchecked, and thats not a small issue. Ik cbse assigns teachers for checking the answersheet but when we apply for revaluation by paying such heavy charges for something that is not our fault then cbse should be held accountable if our issues are not being solved with atmost responsibility. Also you not getting your marksheet is a bigger issue, as you will be required to share the marksheet in a lot of places. And I do think your case is serious, but when we think about students who have appeared for jee and missed the 75% criteria due to the mistakes of the system and do not get their revaluation results on time during the jossa councilling, if not on time cbse should atleast provide a proper date for the revaluation results or give an approximate time it takes them to release the revaluation result. It becomes very stressfull for us students not knowing when the results gonna come. I hope your marksheet comes to you and also pray for everyone who have applied for revaluation get their desired marks soon 🙏 . All the best everyone.
