So I have a really big test coming up since I'm applying to dental schools.

schools want you to apply by the summer to enhance your chances.

test covers biology, general chemistry, organic chemistry, reading, math, and perception.

last 3 subjects are no problem. Biology is just review since I did it recently. I haven't done chemistry in a while but I did learn it so it's just review too.

problem is Organic Chemistry. I'm doing Chemistry 2 next semester so the soonest I could take organic chemistry is next summer.

I want to have this test done before then since I want my applications complete by then. So since I have so much time now I want to study and get it over with instead of delaying but my mom thinks I should delay and wait till I'm done with the entire year of organic chem, but I don't have time. So what to do? Should I just try to teach organic chem to myself and possibly get a tutor?? Ty.

I just discovered it today; a white, hard matter has gathered on the borderline between my teeth and my gum and whenever I scrutch it, it hurts like hell. It also bleeds when I brush my teeth. It is on the lateral side of my teeth, the ones that are deeper, on the left side, on my mandible.

can I do besides going to the dentist? Can I make it go away on my own? If so, how? I am foreign student and I cannot visit any doctor where I am now. Thanx
