@Juul you have literally posted all the questions of AIMCAT 2011 while its been only a day since the exam has started. While it is necessary to get your doubts cleared it is important to understand that you are ruining the exam for others. You can either take the exam on the last day or wait a few days before posting your doubts. Also, taking screenshots during exam?? It is a clear indication that you are not focussed during the exam. Don't know if the strategy is helping you but it is definitely hurting others. I am posting it here because you deleted the post where I pointed it out, without bothering to delete other posts. @vishiac @gsm2780 and all the other people he has tagged, please take note of this before solving his doubts.
