    Im really new at this. The problems question is to write two files Students/Grades. Define the Student and Grades class and use concurrently with the Student class. I may have overuse or underused some things. HELP!!!!!!

    The very first part that I became stuck on was in the beginning: public Student(String n) gave me an illegal start of expression error.

    Well, you've got a lot of problems, and it looks like you tried to copy and paste an old assignment into this one to get it to work (which is a "don't" in the guidelines I posted).

    There are so many syntax errors here, I honestly don't even know where to start. You might want to start over and follow the guidelines, making sure to correct syntax errors you go- it's easy to straighten out one piece of wire, but as soon as you have a drawer full of tangled up wires, it's impossible to isolate any single problem.

    That's not a bad idea, especially if this is a result of trying to mash old assignments together. Follow the guidelines, and you'll be done by lunch (depending on what time zone you're in).
