Upsc preparation requires deep learning of topic ,many coaching institutes and youtube channels continuously repeat same previous year study material many reputed institutes does the same and youtube channels too ,this not benefit you for exam because exam questions are modified yearly but institutes repeat old study material. Best upsc preparation youtube channel is ROHIT SEHRAWAT,

There are many channels on the YouTube for preparation of UPSC but if you go for searching them then you will get confused and end up doing nothing therefore you should have crystal clear concept regarding what is study material you need to followed there for the best channel on YouTube according to me is study IQ for UPSC preparation you can search for them and look at the videos but most of the content is not available really you need to purchase a full course on UPSC which should probably much cheaper than the coaching classes.
