There’s also an instructor in every cohort, so your TA (we call them TLs) is more of a first line of defense. We brought in the strongest design students to be TAs which is why they weren’t very much further in the curriculum - in fact they actually had a different curriculum. An exception to the rule caused by curriculum change.

We brought in contractors to help teach the new curriculum, and one hadn’t adjusted the light in his room for video conferencing and couldn’t see the screen for sunlight, so... improvised. Normally there are weeks of practice lessons and training, so this also the result of a rush.
