i aced all my science exams because of you!! i never understood anything that was going on in lessons and this channel helped from knowing nothing at all to understanding the whole chapter! Thank you so much!
I’m a mum looking for ways to support my daughter and your videos are BRILLIANT. I can understand to support her and she can use the materials to aid her revision. Thank You
Thank you Cognito :) This really helped me a whole lot, I can't focus in class and don't understand but thanks to this, I really understand Yaayy!! Hope this video gets a lot more views 😉 This is the only video that was complete that I could find
I have my first Chemestry exam on Thursday and I can't thank you enough for the extra help with these videos, I came across them while trying to find something that would help with my exams as I was struggling to find out how to study, and these videos help so much Had a Biology exam today and the biology videos helped with that a lot
Cognito, your videos are no joke AMAZING. You explain stuff so nicely and well done in just 5 minutes, and that’s why I pass my exams, all thanks to you guys. This is why i subscribed to you, and please carry on the tremendous work your doing!!! You’re only helping more and more people with each subscriber and view you get, which I think that’s amazing. I’ll start recommending you to people who are struggling with this, and hopefully they will start watching you to. GL!!!!!
Hi, this video is absolutely amazing i am going throught the whole chemisty topic on your channel for my scinece exam tommorow, even though i am jn year 9, in 2 gears for my GCSES i will come.back and use this, thank you so much
i actually do not know how to thank you enough for these videos edit* btw im 15 in year 10 i will update you after i finish my gcses i only rely on your videos, cgp sometimes and past papers for revision so hopefully its worth it because these are definetly the best revision guides to exist
Thank you so much cognito, you help me in chemistry and biology as well math, u are the best teacher and sometimes I just wish that you would be my teacher.I am sure everyone would like that to happen. ❤❤

wow amazing this helped me soo much i have a chemistry test tmrw and you literally covered all the topics like an expert!!! My chemistry teacher can resign now!!!!
so basically, evaporation is easier, but we do not get back the solvent whilst crystallization is longer, but we get back both the solvent and the solute. thank you!!
These are summer vacations going on and I'm sure,thanks to you, that after summer vacations, I'll be a top student in studies. Ahahahahaahhaahahahahhàahahhahahahhaha
I'm year 9 and we've had online school for a while so I haven't really learnt anything since the start of the year and I have a really important test tomorrow so yay 😩🤞🏽

Sir your videos are very helpful. Thank you so much.
These are summer vacations going on and I'm sure,thanks to you, that after summer vacations, I'll be a top student in studies. Ahahahahaahhaahahahahhàahahhahahahhaha
Why don’t you leave everything to dry? Couldn’t there be crystals that are still mixed in the solution that you filtered out??
ull just end up evaporating all of it and leaving the bit of solute to form with defects
I'm year 9 and we've had online school for a while so I haven't really learnt anything since the start of the year and I have a really important test tomorrow so yay 😩🤞🏽
please reply I don’t know what sieving and the mixtures of sieving
I don’t know what evaporation is in mixtures
filtration, distillation and flotation
Tmrowss my exam....reallyyy helped!!
so.. not a single person can hear the music in the background?
or am I just imagining it?
ur such a legend for this
Great stuff my lad, keep it going
Thx for this info really will help me in my chem assessment 😅
