Hello dear, if you want to be an engineer then you need to take science in 11th and 12th with pcb that is physics, chemistry and maths. Then you would have to take jee mains after 12th. Clearing the mains you would be eligible for btech courses and can join any engineering college according to the scores you get . Furthermore you can give jee advance to get a seat in good iit colleges.

With hard work and constant efforts tou can achieve your dreams. Keep working hard.

Good luck.

Hello student,

So for pursuing engineering all the main exams take place once you are done with high school level. At standard 10 there are no such exams,

But yes if you are wanting to join any coaching centre for course of jee mains , hee advanced and all other engineering entrances then there are various tests held which you can give when you are in class 10th or once you are done with class 10.

Hope it helps!
