All intro computer science (CS) classes have Ninjas staffing them, but there are no student teaching assistants for labs.
Notes about Tutoring
Make sure to attend at least two Ninja sessions before requesting an individual tutor.
In addition to reaching out to the professor, you can also reach out to the CS academic support coordinator, Lauri Courtenay, who can help find you a tutor. She is great resource for understanding student problems and knowing what kind of help students need and where to get it.
Tutors can help with conceptual problems, but are instructed not to help with the current weekly lab assignment (students should be directed to Ninja sessions or office hours).
Students can form support groups on their own. Most classes have an online discussion forum via Slack or Piazza, where students can reach out to peers.
