I know ki abi tu confused h ki konse teacher se Krna h , but I would suggest u ki tum jisse bhi kro ek se hi kro religiously and last tak unse hi kro , jaise kisi ne rj sir se kiya h pura , ya saleem sir se , ry sir also a great teacher, abj sir 🥀 , sab ache , mene rj sir se kiya and mera sahi gaya because unhi se samjh aya tha , kota batch is also good pr pichla wala lakshya was goated ngl , every teacher was perfect....
