Insight 2011 Unit 4 practice exam

Has anyone else completed this? Very straightforward but a number of the questions are extremely poorly worded to the point that they're completely misleading. Would be good to affirm that I'm not making this up in my head

not to me :/
i found it to be one of the easier trials
There was a question that i found impossible to answer though, in question 5bi (E.R), they ask you whether pH in the half cell decreases, there's no way to tell this, as they didn't tell us what the other half cell was?

Yeah it was very, very easy, just a few errors in the construction of the questions. That was one of them. I answered by saying that nothing would happen because there was nothing to oxidise hydrogen gas or reduce H+ ions, but then the answer said Fe3+ ions would act as the reductant, which were nowhere to be seen in the question.

Haha i did the same exact thing! Can u remember the other questions that were similiarly flawed? Can't think of any other ones.
