For people who bought vinay uppal's courses, are your doubts being solved completely? How long does it take to get an answer about your doubts?

Im considering buying vinay uppal's dropper course because he also stated that doubts solve hote hai and physics is my weakest subject :') I looked through his reviews on reddit but I havent seen anyone talking about doubts and getting them solved and all, does sir fr do that?

Also, he teaches from complete scratch on his dropper courses right? Would an average student be able to understand his lectures? (I couldn't make a decision on the basis of the free trial lectures provided so socha yahin puch lu )
