2024-25 session class 12 attendance here 👏
Thanks mam it very usefull ❤❤🎉 1:46:02
Can anyone tell me that studying class 12 pcm with class 11 proper barbad ?
same here bro but abhi tak maine bhi kuch nahi padha hain aur 20 sep se mere half yearly exams h lekin boards mein target hain 95% aur vo achieve karke hi manunga bhale hi kuch na padha ho kyonki self confidence hain kudh pe aur padhna jaldi hi shuru karunga
Broo good luck but I want to know that is class 11 really necessary for class 12 pcm
Mam aap ek no. Organic chemistry padhate ho Lots of love ❤❤I wish god gives you lot of happiness which you deserve
👍👍
Thankyou ma'am
Mam u are the best ❤❤❤❤
Thanks. Sir it is very helpfull ❤❤
