I would rather to ....

I would rather to study engineering; although it is the hardest subject but personally I think it can secure my future thus I can find a well paid job.

Hi Samy,
You can study whatever you want, but you had better do it without ‘to’, as in: I had better/ would rather/ would sooner stay here/not stop yet.
Would you rather/sooner become a well-heeled without studying engineering?
