Need any suggest

Seriously, it may sound crazy. I've decided not to enroll university cause i just wanna be a part of Police academy. But, someone ask me ..

"If u didn't pass the test, which one would be your chosed faculty ?"

It was like a lightning strike over my head. I haven't any stockpile about continuing education. I just chosed police academy. Uh, getting down. Need any suggest. Do you have any suggest?. Now, i really need my private teacher. Maybe he can gimme any suggest that will help me and make it all clearly.

God, show me the right way please. Without you, i know i'm nothing!!
