A friend is having trouble keeping up with the class. You suspect bad study habits may be causing her grades to drop.
The problem is her grades are dropping and she might fail the class. You could suggest that she should get a tutor that could help her once or twice a week with studying or the day before a big test. Or, if you have any extra time, you could offer to help your friend yourself after school. One of my friends is having a really hard time in a class that I'm rather good at, whenever we have time to work in class I go over the homework with her and explain it more so it's easier for her to understand. I also have gone over to her house after school to help her catch up on old homework.
