That was an interesting paper to say the least, I know for sure I’ve already lost 3 marks since one of the questions was about NTC thermistors, of course; such a niche piece of knowledge would be in the exam, turns out NTC stands for Negative Temperature Coeffcient, and not as I wrote, Nickel Tungsten Carbide. I assumed since heatsinks and the like were in the ELEC2 that It couldn’t be negative thermal coeffecient. But alas, it was - I actually thought to myself about 40 seconds before the end of the exam that it might’ve been what I thought initially, now that I think about it, I don’t even know if ‘nickel-tungsten carbide’ is a real thing.
Another very irritating thing was truth tables, I mean, they were easy, but the ordering of the letters a few times really started to get on my nerves, for example:
| C | B | A | Q | +---+---+---+---+ | 0 | 1 | 0 | | | 0 | 0 | 1 | | | 1 | 1 | 0 | | | 1 | 0 | 1 | |
Notice that the actual characters A, B, C are all actually switched around, yeah, it was like that for the entire paper, something that was supposed to be easy caught me out twice when I was re-checking my paper. Exam nerves were also awful too, I’d gotten to around Q3/6 realising I’d spent so long reading the questions that I only had about 30 minutes to finish all this other stuff off - and then mark it all.
Everything else was pretty easy and standard, I knew there would be karnaugh maps, and there was, so I’m pretty happy I spent an hour last night revising them. I also felt pretty good writing QED on a 5 mark ‘show that’ question, take that examiner.
