Description:

The test pattern for Biology CBSE PMT and other State examinations, IAS prelim, SAT, AP Biology and NET UGC and related examinations comprises four to five multiple choices for an answer. One could be the most appropriate and right answer and needs to be marked. It is advisable not to answer if you are not sure so as not to lose marks.
