Hi

Sorry for late reply. If you think you can prepare and do well in life sciences category then proceed and apply for it.. look at the syllabus first and question papers I suggest its not a good idea if you are only familiar with half of the syllabus the questions are not just based on one half and they have negative marking so don't risk because its not free they take fees..you belong to health science or allied sciences category and both csir net and ugc net don't have such categories..the closest subject I could find related to yours was the social medicine and community health subject i n UGC net. Now I am a MSc physics and I have applied for electronic science in UGC net many times as it was one of the subjects I did in PG and I was eligible and honestly it was tough because i was not familiar with many topics in the syllabus as my specialization was physics not electronic science but my oversmart friend who loved electronics cleared it after a few attempts so if you are like him give it a try but one more fact was that he was not just MSc physics but Mtech in cryogenic engineering from IIT kharagpur too so he literally did rocket science ... UGC net allows subject closest to yours if not exactly the same. CSIR NET aren't strict either they are not JAM or JEST to make rules tough. If you think you can manage...apply under life sciences category and appear for the exam if the application form has drop down list and it doesn't have your qualification then it might be a problem. Then the application won't go further this way at least you will know if you can give or not.

now last but not the least you don't require net qualification to become a lecturer or asst professor in your field. If its for other purposes you can as well appear.

let me know if you have any other query.
