If you want ideas on how to do well on application tasks, I have one simple tip that should enable you to work out most, if not all, questions you face.
Break the question down. It sounds simple, but trust me, it's the most powerful technique ever created by humankind to solve problems, especially maths problems. Most Methods application tasks look forbidding, but if you get a massive question, first ask yourself these questions:
1. What exactly is this question asking?
2. How can I rephrase what the question is asking?
3. What have I learnt that is of remote significance to the question?
4. What information have I been given, and why do I have this information?
5. How can I make use of this information?
I assure you, if you remember to ask yourself these five questions, you'll have a clearer idea of what the heck is going on in Methods. I always asked myself similar questions when I did Methods practice exams at midnight with a mind that was half-asleep. Mind you, I could still finish exams in 90 minutes and get most questions right with this technique. All that remains for you now is to learn the course and gain some confidence. Good luck! There is no reason at all that you should not be able to do well in Methods.
