Bumbaclart got physics paper 2 tomorrow.

[zoisapeers]

To cognito, thank you so much for all you have done for my triple exams. Whenever I came across a hard topic in school, I thought ‘Cognito will make it make sense’ and I was right! Couldn’t have done GCSEs without it. Thank you!! Your website is amazing!

[vt.physics]

Love the way you explain science with this clean presentation and clear sequence!

[RicardoTai-qzyk]

bro i luv u 40 mins for understand the whole concept for my looming test

[zakariaryanmechkak]

literally learned all the physics content that i didnt understand from my teacher at 3am and my exam is at 9 IMA PROVE HOW U CAN GET 7S WITH 5 HOURS OF REVISION

[doIknowyougoodsir]

TYSM I legit have my finals of this year tomorrow and I finally understood the magnetism chapter all thanks to Cognito🙌🙌🙌

[starlightglitters]

Thank you thank you sooo much this really is helpful as I'm gonna have my papers in this October these videos are heavenly I'll tell my classmates about this channel

[allypallyuk]

Just had my 2022 edexcel physics exam today and these exact sorts of questions were everywhere, thank you so much this was perfect to help me get through them ^u^

[JKR]

Sir I’m kind of sad this is my last time watching a cognito exam 😢 I will get grade 9s in all sciences for you sir thanks so much

[hudernslideshow]

Inputs are in the Primary Coil and Outputs are the Secondary coil.Thank you sir!

[ayanjafrii]

do you have a video for microphones and loudspeakers? it's a concept in this topic that i've been struggling to wrap my head around

[Joseph.Jacob..]

thanks man, really helpful.
may god guide and bless you!

[sabahghouri]

Please make a video on cathode ray oscilloscopes

[nouralbardisy]

Can you please cover the A-level chemistry and biology content as well please?

[Nina-klsv]

I swear to god if you were my teacher I would like become a physics major instead

[mujtabaalasdi]

So when we increase the voltage in the secondary coil we get less current than the primary coil and visa versa, is that right??

[starlightglitters]

Can you make a video on circular motion topic as that's a new topic added to my olevel exam please my exam is next month 😭🙏🏻<3

[JJ-nrdp]

The first question is wrong 45/0.33=136

bro i calculate 45 divvied by 0.33 and my answer was 136.36 is it right or not ?? @cognito
