TITLE: What are some good problem solving techniques for Math Olympiad style tests?
QUESTION [5 upvotes]: I am taking part in a Math Olympiad style test at my school in a few weeks. This test is mainly problem solving based and tests you on topics such as counting techniques, algebra, geometry as well as some miscellaneous topics.
So, I was wondering whether there are any key problem solving tactics to help me solve the questions while at the same time, increasing my efficiency.   
I understand that people have asked a question like this before, however, I am asking for some specific techniques to support me problem solving. 
Thank you :)
