Hello, first of all you should say "hello " or "please" when you ask a question, you will more likely get an answer.
"If I studied hard, I would succeed" means in the present, if I study hard now I would or will succed
"'If I had studied hard, I would have succeeded" is a look back in the past, that if I had studied I would have succeded, but I didn't study, so I didn't succeed!!
