I'm "helping" (?) some high school students with their entry-level
computer science course. They need to write a class file that goes with
the following client file. The final grade is determined by the sum of
the higher of the students's two test scores and the exam. Offhand, I
don't remember the exact cut-offs for the letter grades, but it was
something like: >= 90 A; >=80 B; >= 60 C; >= 50 D; < 50 F.
Any help would be appreciated!
