In a lab today we were working with electronic circuit boards (kind of like old-fashioned Arduinos). I had done the prelab but I had a great deal of difficulty trying to get my circuit board to work in the way it was supposed to. Slowly, everyone in the class left. The next class arrived and I continued to work. I consulted the TA for help several times and eventually I was able to prove that the board I was working on was faulty. It was very difficult, as it seemed to work as expected with one micro-controller, but given multiple some funky stuff started happening. The TA emphasized that it was important to understand the basics and advised me to come back tomorrow to make sure I understand how to use the circuit board. I already missed a class staying in late today. This is very frustrating especially considering I pay lots of money to be in the class and half the labels on the chips are so faded you're not even sure what you're putting in.
My question is, could I have done anything differently (and not missed my next class)? I find it nonconstructive to blame things on the equipment, but it does really happen sometimes. Should I have pressured the TA more for help? It was 1 TA for a fairly large class but she almost never looked at what I was personally doing and just gave general advice. What would be fair for marks? An omission or an extension?
This was embarrassing and frustrating. After the TA told me how I had to be able to do this, I thought about dropping the course. It would have been unfortunate if it was because I happened on a defective board.
Should I have put more pressure on the TA to help me or make sure my equipment was working properly?
