_________________Welcome to Replicating Minds________________________

Myself Sanjay Kumar. I am a Ph. D. scholar in Biotechnology and also I am an online tutor and provide free online classes on my Youtube channel named Replicating Minds. I basically teach topics related to Life Science and Biotechnology, CSIR - UGC NET JRF, DBT - BET, GATE, and ICMR NET JRF.
But I think along with educating everyone we should also provide assistance that how to be vigilant for the other things related to your fields like competitive exams, Universities, Institutes, and available fellowships for higher academic studies. Therefore I also started recently making guidance videos about the strategy, Tricks, and fellowship information. You can watch those videos in the playlist named CSIR DBT GATE Guidance, Information, and Tricks
