I'm just obsessed with this channel especially with roshini mam.... Her teaching is just awesome.... Your my inspiration mam...❤ Thank you so much mam 😊
I have watched alot videos to learn this chapter but I can't..... Finally God blessed me with your video mam 💓 thanks so much for your patience , effort and everything u put for us .... Literally I loved your way of teaching ❤
Mam in the beginning of the jee pe Jeet series, please provide a video on how to prepare for JEE.For example, after compelting a chapter , what should be done apart from ncert ...Please also provide a timetable mentioning what chapter to study .I hope you will definitely respond to this . AAP ek video dal do jaldi taki we can start preparing during these holidays itself Thanks in advance mam
Time .1.17.54. Pe PV graph me kuch galti hai. There u meant to explain volume constant, but in the graph shows pressure and volume linearly increases. Plss once check
Mam please update the one shots videos becoz jo syllabus delete hua tha by cbse vo apne one shots m include nhi kiya but vo competitive exams m ayega 🙏🙏
Greetings ma'am , please do make a video on chapter 14 - Waves .. Love your way of teaching , concepts are easy when you teach! Thank you for these amazing videos :)
1:58:53 wasn't that change in temperature to be taken is to be 20°C,since its mentioned in the question that to rise temperature from room temperature i.e 25 to 45°C,also i have the doubt that why aren't we using kelvin to solve numericals which is SI system.Thank you for your video mam by the way....🎉

Teacher acha hona chahiye agar teacher achi hain toh sab kuch samajh me a skta hai roshni mam se padh ke bohot acha lagta hai line by line jab learn karna shuru karte hain har cheez ka visual araam se dimaag me ata hai aur sab yaad ho jata hai thank you so much mam
Mam aap neet 2024 ke lei new videos kab se start karo ge subject physics and chemistry please jaldi se new videos for neet 2024 ke lei start kar do thanks
