recently after covid, i was failing my subjects, well at least math and getting below average marks in pcb. I relied on your content for a while and used your website to practice past papers and the quizzes. i have improved in math and got a 71/80 in my sciences. somehow one of the teachers suspected i had cheated and took a extra test just for me. it was shorter than my previous one but i still scored a 45/50 on that test. I really appreciate your hard work that you do to make these videos. i hope you can now also implement AS and A level courses soon. Anyways thanks a lot for all that you do. - Just a student from India

"- Just a student from India" Man I feel you. The teachers in our schools are so preoccupied with things that _aren't_ about studying these days that I fear for what the future generations will have to go through. I'm sorry that you were suspected of being a cheat and for what it's worth, I'm happy that you showed them what's up with that 90%.

Just thank you for the work involved here - my O levels are well behind me but this work makes me so jealous of all the youngsters who can get such a great start to their chemistry lives. - I'm on with the rest of the series so my weekend is fixed up nicely.

if you know the atomic number, eg carbon is 6, the inner shell will get 2 electrons, the next shell can have up to 8, since carbon has 6 total the remaining 4 electrons are in the outer shell. in this video he was talking about chlorine, which has atomic number 17, meaning 17 electrons, first shell gets 2, second shell gets 8, outer shell gets the remaining 7. hope this makes sense, also open to citicism, im new to all of this, just trying to figure things out like you!
