Extra Credit

cse365-2026-summer
0/24 challenges completed

This module contains optional extra credit challenges for CSE 365.

Each regular course module has three extra credit challenges: Easy, Medium, and Hard. To receive credit for an extra credit challenge, you must complete one CTF Archive Challenge Reflection after completing that challenge. Each reflection should take about 5 minutes and briefly describe what you did and what you learned.

Module extra credit is capped at 40 points toward the regular 800-point course total, for a maximum final-grade boost of +5 percentage points. Additional extra credit challenges are available so you have flexibility in how you reach this cap, but completing work beyond the cap will not increase the final grade further. See the syllabus for more details.
