Honestly, Ive been so bad with my science, even until now when I am in year11. I`m getting grade 3s and 4s in science which I don't like, but I`m never going to give up. I`ve only watched 3 from the start of your chemistry playlist and I`ve learnt so much. I love your videos and as coronavirus has stopped exams, I can try harder to get grade 7s. Thank you so much!!!!

Hi , thanks a lot for all this information that you put in the videos , last year I submitted a biology and I passed in it , all I did was prepare for the exam by studing your videos . Thank you for the helpt that you provide us in the simplest way .

The video series so far is very well explained, i like the fact that you are not in a rush to overwhelm us like most other channels. It feels like i can genuinly learn and digest the material, my compliments and thank you!

@garlicbreadstick404 3 ай бұрын

Ive always been interested in science and ive recently started learning this topic. But our science teacher does nothing but berate how much of a dumbarse we are compared to his generation, with only 30% of the time spent on teaching us. So here i am scrolling through google and youtube for a teacher that actually cares about their students. Love your video!

because some substances have different melting and boiling point than others which makes them a mixture without being chemically bonded
