Hello sir, aaj mera Physics ka paper tha objective type. Aur aapke videos ko dekh kar maine bahut sare concept cover kiye the. Aapke videos k help se mujhe lagta hai ki mere 150 me 100+ marks aa sakte hai. Agar aap youtube pr itna acha content upload na karye to shayad mujhe 150 ke 100+ marks ki ummmid na hoti. SO THANK YOU SO MUCH FOR YOUR VIDEOS.
