Kon kon class 10 th se ha 🙋‍♂️ ( as a senior I would suggest you all please study this chapter seriously otherwise you will feel difficulty in class 10 th )

Newton's fourth law-
Every book continues to be at rest and covered with dust until and unless internal or external exams appears.
The speed of page turning is directly proportional to the syllabus to be covered, but tension remains constant😀😀😀

Exam is near😢
Nothing is clear😒
No need to fear😅
Because PW is here🎉❤

She deserve "Queen Of Chemistry " .
Plz vote for She
*Those who are agree * 😊😊

Kon kon class 9 me hai agar app class 9 me ho to (please study this chapter seriously otherwise you fell very difficulty in class 10) ok ! 😊

Amazing, I'm currently 12th appearing students preparing for jee, mai apne kuch chote bhai behno ko kuch batana chahunga jinko padhai me bilkul intrest nahi hai aur wo soch rahe hai ki 10th se padhunga ya 11th se... let me tell you my story, mujhe chemistry se kaafi nafrat tha aur phir kya mai 9th, 10th aur 11th me bilkul v chemistry nahi padha, by the way mujhe study me bilkul v intrest nahi tha and that's why mai padhna jaroori nahi samjha, mujhe technology me kaafi intrest tha aur maine different different programming language (python, bash, sql) and web designing sikha, mujhe padhai likhai sab bakwas lagta tha aur mai sochta tha koi jugad karke 12th kar hi lunga phir college life but dost mujhe bahot late realise hua ki mai galt track pe tha aur mujhe kaafi regret hai is chiz ka ki mai apna 9th, 10th and 11th waste kar diya, there is no substitute agar aaj nahi mehnat karoge to kavi na kavi karna hi padega aur jab karna padega tab bahot jayada karna padega aur ush time tumhare pass koi aur option nahi hoga like 9th, 10th me nahi to 11th 12th me aur agar yaha v nahi kia to.... Kuch v nahi keh sakta🙂 Wish you all the best guy's, fod ke rakh do 😊😊😊

Newton 5th law
The rate of increase of tension is directly proportional to the incoming date of exams 😂

[SD_BHAI_]

Why this type of teachers and this type of energy and efforts our school teachers put in explaining us!!! 💔🥲..
Same 💔
👇🏻

Great teaching.
I cleared all my doubts.
Sanya ma'am is queen of chemistry
