These exams are different to other exams I had taken. Conceptually, the questions are not crazy difficult, but you do have to look for ways to answer them quickly. So, from what I can gather from my own and others experience - time management is key.
You can practice this by working out the average time that a question should take (a 3 hour exam of 30 questions means you have 6 minutes per question) and redoing the answer for a question until you can do it under six minutes. Sure, some questions may take 7 minutes and others 5 minutes but you have to average 6 minutes. You can break down practice exams into bite-size chunks, say 5 questions each, and make sure you can get each chunk completed in 30 minutes. If you can't, look for where you took the long way to work out a question and drill into yourself the short way. Don't forget - you don't have to get 100%. If the pass mark is around 70% you can afford to drop 1 in every 4 or 5 questions. Just keep that speed up - if you have no hope of completing a question within 6 or 7 minutes, abandon it and move onto the next.
