Best driving schools and red flags to avoid !!!!

I'm considering learning to drive, but I don't have any personal recommendations or contacts to ask for reviews of local driving schools. A Google search shows several options, all with impressive ratings (500+ reviews, 5* or 4.9*). Are these schools genuinely that good, or is there more to consider?

Most schools seem to offer similar packages: 15 days, 30 minutes per day, with free pickup and drop-off, priced between ₹3.5k and ₹4.5k.

Also I would appreciate if anyone can tell me what to lookout for when joining a driving school?
