Tutoring Services: Supplemental Instruction

Tutoring Services and Supplemental Instruction available at Tri-County Technical College.

What is Supplemental Instruction (SI)?

Peer-led, collaborative, review sessions for traditionally difficult courses at Tri-County. Even if you're not enrolled in one of the courses below, the collaborative SI sessions can be beneficial for any TCTC student. 

These sessions are facilitated by an SI leader, a fellow student who has taken the class and earned an A. They will offer another way for you to engage with class material.

  • Accounting 101
  • Biology 101 and 113
