Hey I took my booklet home so I had to check it just to make sure that error actually was there. I'm surprised by that and I think it is a bit dodgy on behalf of the BOS but the error there doesnt ever actually effect your answer to the question since your not asked to desk check the algorithm or anything.
You only have to describe the purpose of the variable, describe what happens when j is initialised to 1, which is not at all concerning or affected by the part j = j + i. Then you construct the other sub procedure.
So really theres nothing to complain about since, if you did the question right, that error should not affect your answers. When answering the question i didnt even notice the whole line j = j + i since you dont really need to look at that when answering the questions.
Thats my view, and I for 1 would like that question to still be counted since im pretty sure that was one of the few things I got right lol
