No one can doubt the material provided by PMFIAS. It's one of the best or in my aspect i would say the best but as we do in UPSC i will critically examine all the material.
For Science material i would say:
1) NCERT Compilation : It's really good for improving basics and may be helpful in prelims for 2-3 Questions
2) Science Current Affairs --> it's good and one can expect some questions in prelims directly or indirectly from it.
But what can PMFIAS can do to make it 5 star and best product in the market:
1) Upgrade your static compilation by including topics like Particle physics, ICT and Biotechnology --> these should be top in priority. After that it should focus on space, defence, nanotech, robotics.
2) It can take reference of Books by HS SIDHU and Ravi P agrahari. Even 10 out of 11 Questions in UPSC prelims can be solved out of it.
Rationale behind these recommendations:
1) upsc is increasingly focusing on these topics especially particle physics in mains, ICT in prelims, and mixed focus on Biotechnology.
2) Recommendations are based on practical analysis of PYQs, So, it is not just based on feelings.
Last thing i want to recommend is Please complete your topics on time. On this front you lack a lot to achieve your potential to be the best product in the market. and for best you can make and provide video lectures. That would revolutionize your market standing especially if you provide in video lectures in English and Hindi language.
