I feel that these videos are improving me every second (no time wasted while getting entertained!)

You taught me better than my qualified teachers can 💀 (Actually ONE of them can teach thankfully but you summarise it all for me easily.) Thanks a lot! ✨

[jellyknows]

Your channel is very very very very useful for us students. I mean really I understood everything in the first minute. Which in school in takes like 20 minutes of my teacher trying to explain the same concept over and over. Thank-you 💕

I can’t lie you just explained enzyme models in 20sec whilst my teacher took a whole 1hr period !

I absolutely love what you have done with making the whole playlist and practice questions and tracking, its literally made life easier by 100%, THANK YOU 🙏

Hey! Just wanted to say the website has been amazing. I usually get 55 percent ish in my bio tests and I used it for practice paper revision and got a 70 on my last test. It’s really helpful. Great video!

The only video that talks straight up without waste of time

[bradysmudge]

thanks! super clear, didn't get taught the induced fit model in school!

[simplyscience]

Great video! Your videos have inspired me to create my own educational youtube content to help students with their GCSE science.

[WEEBWHOSELLSWEED]

Amadeus, can you please speed up the making of your CIE course, I would really appreciate it.

So in the case of induced model, how enzymes know what specific reaction they speed up?
