i have prepared my notes from various sources

guys paper seems very easy and the topics also
shall i opt for it in ce-13. and replace it with geography as it's happening to be a disaster for aspirants...?

if you have background,then dear go for it......its an scoring subject.

1 background
2 read well and make ur own notes

Confusing
 
I can solve this paper up to 50 to 60 percent without preparation but the question is that why they specified the topics, narrowed the questions and mixed like they also asked about Glomerular Filtration and filtrate. This is Pure Clinical Biochemistry and which comes in Biochemistry and Biochemistry under head of Chemistry not Zoology.
those who are little bit away from science it can spill their energy far away from them.

You have to draw diagram where examiner has specified like if there are questions about circulatory, excretory, nervous system then you have to draw diagrams.
