My answer is very similar to yours, except for the * before EF. I get it at the end.
I'm guessing there's some discrepancy with the preference of / * + -

OR, there's some rule with regard to popping from the stack that I'm not aware of.

Also, this is the first year they introduced complexity. What kind of questions can we expect and what exactly should I study?

In this solution I think Question 6 a) is wrongly solved...
In the third row of the truth table,there are even number of 0's(i.e 2),so why is the output 1?
Can anyone confirm it to me please?
