AQA A-level Computer Science Paper 1 - 11th June 2025 [Exam Chat]

Did anyone else see a contradiction on question nine with the scoring in the example and how it said it should work

What was the way of making it left associative for the exponential question?

yeah as long as it was bigger than all the others you’re good, i put 6 just cause the others went up in 2s

Section D was great but there were some weird questions in Section A

did allright tbh couldve done better, i spent too long prepping for adding brackets last night but felt fairly prepared, brushed up on theory stuff before bed and lucked out on it tbh. section b coulve gone better spent too long on it and somehow kept crashing it but got a valid output in the end. section c had some wierd questions imo not too bad and flashed first 3 of section d leaving indecies left starting coz i didnt read the question properly (due to lack of time left lol) and got just over half of the last of section d done, i think its enough to get 7-9 out of 14 on it, i think ive got between 70 and 80 on it in the end

I did something like
for i in range(5):
for j in range(5):
for k in range(5):
for O1 in "+-*/":
for O2 in "+-*/":
result = EvaluateRPN(ConvertToRPN(#Concatenating the numbers together. too lazy to type it out #))
if i != j and i != k and j != k and result != -1 and result in Targets:
return True
return False

I got -49

What was the dollar symbol in the regex? Might have gotten it wrong. Also what did people get for the question on the number of combinations (the last one?)
