Should I use apps like Unacademy, BYJU’s, or free platforms for preparation?

Choosing between paid apps and free platforms depends on your need for structure versus independence.
Paid apps like Unacademy or BYJU’S provide a "all-in-one" experience with scheduled classes, mentors, and test series. They are ideal for beginners who prefer a guided roadmap and can afford the premium.
Free platforms like Sleepy Classes Youtube, Mrunal.org, Insights on India, and YouTube offer high-quality content but require you to curate your own schedule. This path is perfect for self-disciplined learners on a budget.
A smart compromise is using free resources for core study and paying only for a professional Test Series for evaluation.
