I spoke here with one of the group members who came back after the academy:
He: And we also gave off microelectronics offgenically in the second course...
I: Okay, microelectronics and so I gave it cool. I didn’t prepare at all, I slept for 4 hours.
He: No, it is all shit. We approached him before the next session, he asks us type "what is pn transition?". We don’t know the type. He says come next time. I’ll come back to him in two weeks and he’ll ask me another question. We were like "and you asked last time what is pn transition...". He said "Now okay, what is pn transition". And we don’t know what it’s like (three of them).
