Keep in mind I really wasn't a TA. I was a normal student learning the material with the rest of the class and taking exams, doing projects and getting scolded by the teacher as was everyone else. Most of my extra "teaching" was from study groups with my peers and people simply asking me for help during lab sessions because I would simply finish my task in the first 10-20 minutes of class and then I'd either have fun online on flash games, work on my personal projects or simply laze around for the rest of the class (usually 2 hours lab classes) so.. might as well help if people need me. That's a big difference, a "TA" or authority figure usually is more intimidating and less relateable for young students, where an actual peer is more likely to keep them interested and have them learn.

But yeah this is as I said an outlier.
