Mam u are such a great teacher na that i have a no words for u
When u teach us chemistry it, s just look like that u r telling us a interesting story and our doubts become crystal clear 🙂
Thanks a lot for showing so much efforts specially yr efforts for the animation due to them I clearly understand every concept, and my imagination becomes
Once again thanks❤ a lot🌹🌹🌹

Mam one request pls aap ye mat bola karo ki agar nhi aata toh woh video dekh ker aao . Mam itna time nhi hota ki 2 -2 ghante ka hum dusre oneshots dekhe . Aap usi video mein thoda sa theek se bata diya karo . Bhot hi rare bacho ne 11th theek se padhi hoti hai . Toh aap agar bata doge ussi video mein toh kya ho jayega . Ek teacher se bacha 100 baar bhi puche tab bhi teacher batati hai na toh aap bata diya karo beshak lecture thoda bada ho jaye koi baat nhi . Warna smjh hi nhi aayega toh lecture chhota rkh ke bhi kya fayeda

Let me remind,
A redox (reduction-oxidation) reaction is a chemical process where one substance loses electrons (oxidation) and another gains electrons (reduction). It's like a transfer of electric charges, where one becomes more positive and the other more negative.
Thank you ma'am 😊😊😊

[KS-tkdh]

I was literally ignoring this chapter from past few weeks because i felt it as most boring chapter in 12th.
But watching your this video i felt it's not so boring infact one of the interesting chapter in 12th.
Thankyou very much
Everything was crystal clear and now i am completing ready for my preboards.
God bless you for giving free education 🙏🏻😊

[soumya_rranjan]

For those who can't remember oxidation at anode and reduction at cathode
Just mark that Oxidation and Anode start with viowel and are related and other two start with consonants are co-related

[ritu__]

Believe me, now I'm realising that you're doing a great job, covering all subjects (pcm) is not easy

[nezuko]

mam, i've been watching your videos back from the day you channel was callled exam fear and i was in 7th -8th grade. now here i am watching your videos in 12th standard too. you are a great teacher, teachers like you are rare.

[kashafpathan]

Boards 23-24 students mark your attendance here 👇🏻... best wishes to all!

[himanshiarora]

oxidation and reduction memory tip:
oxidation : a in oxidation means anode
reduction: c in reduction means cathode!
❤️

[somsrays]

Being a chemistry teacher, I watch your videos so that I can teach better.

First of all there is no publicity or hype like others do. Directly into the topic is a plus in your videos.

Clear ideas, good handwriting and diagrams, your appearance and a very decent explanation keeps everyone watch your videos..

[Jus.Potato]

💀2024-25 batch legends, where are u🌚👇🏻?

[vaibhavtaneja]

I am myself a chemistry teacher watching ur videos hv helped me in teaching in a much easier way.God bless u

[Swarajthakur]

Roshni ma'am is giving roshni to free and quality education

Thank you ma'am
Edit: Thank u for these many likes
Never got before

[omishapriya]

Dear Roshni Mam,

Mam actually l am a law aspirant, but still took science according to my parent's opinion : l
Initially, starting from class 11th l found everything so much tough, as all the coaching centres were closed due to lockdown that l can't explain my helplessness in words : (
But, then I found this channel providing free education and your one shot videos really helped me to cover whole syllabus in a very less time and making my concepts crystal clear! And I am preparing for my boards only from this channel : D
Really Mam Really, I am very thankful to you from bottom of my heart and I don't know many number of times I ought to thank you!
Thank you so much Mam : )
