Reapplying for Resident Visa

I recently applied for a resident visa, but because I missed a lot of hours in uni, I might get rejected. If my resident visa gets rejected, when would I be able to apply for another? What is the procedure to be able to apply for another resident visa?

Sorry for posting so much, I created 3 new topics already, but I wanted to keep them separate so I get the questions as concise as possible.
