Hi A320sRcool
Firstly what I did is always work out the head and tailwind. Easy enough because all you have to do is turn the wind wheel around so you see the reciprocal of your outbound heading. Of course taking into account drift angle, variation and deviation if need be (it seems that usually you get given the true heading, at least in my exam it was always true heading so no worries.)
Remember that there are only so many ways they can ask the same thing, they can change the numbers to try and confuse you but that's about it. If you make it a habit to always check head- and tailwind then that makes one less opportunity for the examiner to catch you napping.
Secondly sign up for Bristol Groundschool's online database. Excellent value for money and it will really help you practise those kind of questions.
Good luck!
