Assalamoalaikum wr wb! just wanna share a tip [an advice from my friend ]...i found it helpful.. start solving chem mcq paper from the last question and go back wards.... start from Q:40 and go backwards till Q:1 i used to run out of time when solving the paper, and i tried doing this and cudnt believe i was able to complete the paper in abt 40 minutes -- leave the calculation questions and do them after finishing the rest...it'll save time.. -- for section B If you are 100% sure that 1 is wrong just mark the answer C and if you are 100% sure that 2 is wrong , just mark the answer D If in the end you have time , you can go through the other statements and check...but make sure before doing this, you're more than 100% sure ....[there are questions where it's rather obvious the statement is wrong.. ] and also if 1 is correct, dont waste your time checking if 2 is correct or not...jump on to statement 3. If you're really sure it's wrong, then D would definitely be wrong, ans will be D and if you're sure 3 is correct then 2 will definitely be correct, and ans will be A. May be this'll seem a bit foolish, but trust me, it does get your answers right, and also saves your time. After finishing the paper, if you have enough time, you can check the other statements etc. It helped me, and might help you...inshaAllah.. Remember me in your prayers. May Allah give us success in this world as well as the hereAfter Aameen..!
