Question for one who is good at math?

So the end of the semester is getting closer, exams are getting tougher, and I'm getting less time to study. My last exam in my medical vocab class, I only got an 83%, which is enough to decently screw my chances of getting an A. But I want to know what my numbers are. So if you can solve this, I will love you.

I currently have a 493/543. The final total in the class is 749 (so 206 points left in the semester). The entire class grade is made up of exams/quizzes. I need a 92%, minimum, to pass with an A. The teacher doesn't round up. What is the MINIMUM I need to score out of 206 to pass the class with a 92%?

Thanks in advance. I just want to know if I should continue to bend-over backwards to try and get an A in this class, or if I should lay back a bit and put that time/effort into my other classes. Thanks again!
