Your passion for teaching shines through! Inspiring.✨""You made learning evolution enjoyable. Thank you!" "I'm excited to learn more from you, Roshni Mam.❤ thanks a lot mam 😇
Thanks a lot ma'am! I was searching for this ch and wasn't able to understand it by any other channel. And tomorrow is my exam. This is surely a blessing. ❤
Thank you so much mam for providing us moneyless best education!! U r one shot videos were very useful for my exams &one day battings😅..u nd u r videos r one of the reason for my good marks in inter 1st year exams!!!.. Lastly concepts r crystal clear mam & THANK YOU SO MUCH MAM🫡🙏
😍.... Thank you mam Our class teacher said this chapter has nothing other than memorization...that made so boring But studying with you seems everything precious and valuable.... Thanks a lot❤❤❤
You are doing too good mam...like no other teacher uses this technique of giving examples like yours... your method of explaining by using animation is excellent....i can understand every topic very easily...not only in this chapter but every chapter you taught❤️✨
Hey 12th graders. Just know that this video is not enough. This is just Superficial knowledge. I studied evolution just from this lecture and when i got the question paper in my board exam i solved every question of other chapters which i studied deeply from seep pahuja. The only question i could not solve was from evolution (got 97/100 in biology). So just watch this video as a revision and study from somewhere else.
these chapters are somewhat boring isliye concepts samajh hi nahi aa rhe the, but mujhe pata tha sirf Roshni mam hi aise chapters ke doubt clear krwa sakti hai💫💫
