Hello aspirant,

Don't worry keep calm everything will be ok.

For becoming engineer you only have to score good marks in 12th and jee mains .

But by chance if you didn't get good marks in jee mains than also don't worry there are many colleges which allows the students with less marks also in jee mains.so you don't have to worry about it, you focus only on the study of your recent exams and don't get depressed. Many people are there who didn't get high marks and are engineer today. So don't worry just chill.

Hope this helps you

Feel free to ask any question

All the best for your future
