What's the difference between an A and A+?

So our result is out. I got 4 As, and an A+ for Basic Accounting.

So 4 As and an A+ equals to 4.0

So if a person got 5 As, he/she gets 4.0

What if a person gets 5 A+s would she/he gets more than 4.0?

Anyway, I got CGPA of 4.0. Too bad, I have nobody to celebrate with.

And I don't tell anybody in my family. Especially my mother. She would say "Yeah, you're clever, but WHY DID YOU QUIT MEDICINE?"

Actually, I didn't quit. It's more than 7 years, which is the maximum/limit for medical studies. Well, who the heck came out with this stupid idea?

And most people thinks our Medical school is like Medical Schools elsewhere, where one can just continue their studies after umphteen years of sabbatical. "Oh, it's only one semester, you can continue next time once you're comfortable enough to go to the hospital..." one would say.

Unsolicited advice. It's impossible in the land of 'possibility', 'doablility' and 'canablility'.

If changing to another university with medical school is impossible, what more to say extended years?
