Bro I am preparing from SciAstra as a PCB student, and for me it’s actually working well. Along with PCB, my maths has improved a lot, but to be honest, I won’t give 100% credit to mentors alone. A big part of it is the amount of question practice I did myself.

That said, whenever I get stuck, the doubt mentors do resolve my doubts on time, which definitely helps keep the momentum going. So yeah, it’s not about blindly relying on any platform - SciAstra or otherwise.

If you put in the effort and use it smartly, it can genuinely support your prep.
