CBSE 2010 Class Xllth Biology Sample Papers
Biology, a must have subject if you want to pursue career in medical stream. People say that biology is very tough as it only has to be crammed, but I say biology is very simple if you know what you are cramming. Moreover if you have PCMB, no doubt you will have to put in a little extra effort but it will open up the gates of both medical and non medical streams. From my personal experience I say, managing PCMB together is not difficult at all if you know what you are studying and why you are studying. It may happen that you do not get through in medical entrance examination, then the gates of non medical stream is still open for you. The key to success here is planning and successful implementation of your plan.
