Guys,as it is exam time.i thought i'd get useful by putting up something useful....
First, if you are unsure about an answer tackle it like this......

2.If you dont know anything,then never accept it write something as if you knew everything,like.....
3. If you are given choices in the answer,then the answer is staring at you,..if you dont get it,its a shame...so better take a chance,or of course logical inelligent guesses!!!

4. When you are asked to write something ,better find a justification so that you wont have to!

or........tackle it in this revolutionary way!!

5. If you get a question ,make it appear meaningless ,so that no one is the wiser!!!

Well, guys that is just for the fun part of it ,anyone having really good experiences like that with exams can share them also in the comments part......and better suggestions welcomed!!
