Sir 11th orgainc k continuation me hi 12 ki bhi organic karwa dijiye .. baki sab samajh aajata hai ..par organic ke liye apki guidance chahiye.. And Thankyou so much sir..you've been doing a great job in the history of educational videos. Thankyou sir. No matter when you complete the syllabus, we'll always be lucky to have a teacher like you. 🙏 I've studied in aakash and atleast in my case..they just ruined my physics and chemistry. You came as a light of hope. Thankyou sir. 😊🙏❤✌

i really wish he could be my mentor... Eve though my curret teachers are really good, our class is spoilt by the over enthusiastic guys who have already studied a lot beforehand and are just better... They increase the class pace like anything... In real world, the RDS is not always the slowest XD!!!
