Should I finish my secondaries this late in the cycle or withdraw my application and wait?

I've already received a few secondaries (like 5 schools) but wondering if its a waste and if I should withdraw? My stats are 507 (score from 2022), 3.6sGPA, 3.75cGPA? Would it be better to withdraw and then apply for the next cycle? I'm new to the DO process and I'm still figuring out the timelines?

Also, I probably would need to retake my mcat to get a more updated score?
