TDP again

So yeah, it was TDP. My partner and I were designing a circuit for a microcontroller. We’ve already done our schematic on Capture and we’re ready to make the design for our PCB on Layout. Before we started, I asked a colleague if I could check his work to see if I missed something on the connections (I could’ve made a mistake while copying the design from the blackboard). Then our prof came to me and said in a loud voice, “Why the hell are you copying from [name]?” I told her I wasn’t copying and told her the reason why I was looking at my colleague’s work. My partner backed me up but then she said, “I’ll send both of you out of the laboratory.” God. For the 2 whole years I’ve been on that lab, I’ve never copied from anyone.
