I got 94% in non medical in 12 class. I neither want to become lecturer and engineering. So for what course should I apply in du?
As you have deducted two options from your career that is lecturer and engineering so now you have to first identify you interest and then choose your domain accordingly as there are 'n' number of domains available.

You scored good percentile in 12th so it seems you are good in studies so you can also go for competitive exams like UPSC, state PCS or banking which are great career opportunities.
If you like some subject like physics or maths then you can also go for graduation in it like bsc in maths or physics . Also if you are interested in humanities then you can shift towards arts side and can do BA in that particular subject.
You can also go for some computer fields like BCA and BCS . If not then also you can do animation,graphics,etc which is also a good option.
If you like chemistry then you can also go for pharmacy .
I want to just suggest you please first identify your interest fields and then I can suggest you domains according to it because the list of domains available is never ending.
I hope you are satisfied with my answer. If not then please be free to ask again.
Thank you!
