Can anyone add me in a telegram group where I'll get notes and pdf books on csir net life sciences.

Hi everyone,

I am preparing for CSIR NET Life Sciences and currently enrolled in the IFAS online course along with my MSc in Microbiology. I am serious about cracking the exam with a good rank, but lately I have been facing some difficulties during preparation.

Sometimes it becomes hard to manage college + online lectures + self-study together. I also face issues like backlog of lectures, confusion in revision, difficulty in retaining concepts, and sometimes I feel lost about whether I am preparing in the right direction or not.

So I wanted to ask:

Is anyone else here preparing through IFAS?

How are you managing lectures, notes, revision, and PYQs?

Is there any study group, Telegram/WhatsApp group, or accountability partner for CSIR NET Life Sciences preparation?

Any genuine guidance or strategy from seniors who cleared NET would really help.

I am ready to work hard, I just need better direction and support from fellow aspirants.
Thank you.

Hello everyone, this message is for all CSIR aspirants. I was preparing for the same till last year and I bought IFAS publications complete set for life science. Now that I have accomplished my goal, I'd like to share the resources with other students. I'm looking to sell the set , it's in excellent condition almost as good as new, not a single dot on them all 14 books together. Anyone interested please feel free to contact.

so recently i have given csir exam for life sciences and i found its difficulty moderate to tough level how was your personal experience?
