We've all been there — it's the night before an exam and you just can't figure out how to solve that equation; your research paper hits a dead end; you're sitting in lecture and are completely overwhelmed by how confused you are. All of a sudden, you're wishing you'd asked questions or talked through your ideas with someone earlier.

Who better to help you out than students who have taken the class before you? How about someone who's helping teach the class now? Enter teaching assistants (TAs) – they're students, like you, but they know what professors are looking for, too. Sometimes their job is to help lead discussions, other times, they grade papers and assignments, and in some cases, they even teach sections of courses themselves.

But no matter what their role is at your school, they're a great resource for you. Five TAs shared their advice on everything from note-taking to thriving in the classroom this semester.

1. Prepare before discussion sections

"The most important piece of advice I have is to do the readings before class, so you can really concentrate on understanding what the professor is saying without scrambling to write everything down," says Maïté Van Hentenryck, a senior at Brown University and neuroscience TA.

The same goes for recitation sections.

"Focus on listening to the TAs instead of taking notes because many times, they go over major concepts and it's important to fully understand something, not just think you do," she advised.
