thanku sir or this valuable information
great work by u sir pls ek baar live class me bhi leke aayiye
sir , aap 11th physics ke course nhi bnate kya because I read in 11th class

thanks
sir will u send me this formula pic on my whatssapp no....9858753333
thank you very much sir..wo formula track ..bahut badhiya hai..pura padhne k liye maza aagaya..aap issi tarah sare chapter ka formula track de dijiyega sir..bahut beneficial hoga..humare liye..neet k preparation k liye.
