Couple of notes, as requested as a comment: (I haven't read the grading paper yet). Question 11: Compiler and Run Time, I think they're probably looking for compiler and interpreter there. Question 13: the thing that stands out to me is that there are two navigation elements, one on the left, and one along the top. Question 14: I suspect they are looking for a peer to peer network as the answer here. It's possible they are looking for something more like a distributed network, or DHT's or something, but going with the easy simple answer, it's probably peer to peer. Question 15: e: i: I suspect the validation they are looking for is, is exists, is string, is in the Airports table? Part 2 is where it gets interesting, I've never used the term exceptional and extreme, but for this case, (input a number), i'd read exceptional to mean things like "a", i.e. totally the wrong type, and extreme to mean "9999", i.e. out of range but the right type. Question 16: It's asking you about line 2, so it's just a case of get number 2, and check it's greater than number 1. They've not shown any view on the type system, so I'd skip that, it's probably overthinking. The same for b, I think the data type is probably number or integer. Question 16: b) I think they're asking about nagivation, so the design might be a tree menu, on the left that unfolds? I'm not sure what langauge they'd use to describe that though. Tree navigation? Question 18 d ii) I think you are overthinking it, that question scores 2 points, so I think they are looking for score = score + 2 as psuedocode. Question 19: I think they are trying to understand if students understand vairables. So the extra points here are about explaining that SET total=total+cost is going to read the current total, add cost to it, and then store it back in the memory location pointed at by total. Part iii, I'm also totally stuck on. I thought at first it was a trick question, if she's changed the array data, after the code has run, she needs to re-run the code. That's the best I could come up with. Quesiton 21 c - I think the missing one is edge case here. The number of players 4, games 3, is the boundary condition, so it's one of the ones that's likely to have a bug (off by 1 errors are common). I think the number of players 6 is abnormal, but they might mean extreme, who knows. I'm off to read the marking criteria to work out whether I'm right as well 🙂
