I am currently doing my final GCSE exams but I am worried that I will have to go through A levels without finding cognito videos to save me :(
Can you please do A level videos?

Just in time for my Bio P1 on Tuesday!

[torielschild]

Thank you for your efforts!! These videos have really helped me feel caught up in time for GCSES this week, after being away from school for some time, so thank you so so much!

[aivy]

Thank you so much, because of your videos I actually do well in exams and understand the topics we need thoroughly!

[ibrahimbilalzahid]

Bro your one of the best teachers. I promote your videos in my school. I convert ur videos into notes and my friends compliment them on how easy they are to understand, thank you.

I've got my end of years in about 3 weeks and I've got a lot to revise but these videos are incredibly helpful! Thanks cognito!

I was training to become a maths teacher and I found your channel when I was looking at how to explain things, now I watch your videos for stress relief XD love your calm explanation, the colours you use, and the way things are presented. Thank you so much for creating such amazing videos! Just out of interest, do you write/draw all of the text and images by hand?

[dharmgajjar]

My god, I can't express my gratitude, I've been using the Cognito platform to revise for my End of Year Exams and its helped significantly. Thank you so much!

[EmiSKZ]

as a non native English speaker I'll really appreciate adding subtitles to your videos because the accent could be hard to understand sometimes

[shooshoo_]

Thank you! My finals are coming up and this Channel has been very helpful! Keep it up :)

[MuhammadUsman-nlbb]

The only source for me to prepare for olevel exams is your channel

Your videos deserve more likes!!! I do hope they help my gcse carry on the videos! These also helped my homework 😃

[Razorflash]

I just want to say that I’m really grateful for your help in both Maths and Science although I don’t watch often, and I’ll 100% be using you way more when I actually do my GCSE in 2years time.Thank you so much sir❤️❤️.

[antonroy]

Great video yet again from Cognito. Cheers Amadeus!

[isisgerladhitzgeral]

Is this all you have to know about this topic if you do foundation or do you have to do levels of organisation in animals and plants too?

[Aneesah]

Thank you for creating and producing your videos. They are a massive help to me, especially for my learning style: simple and concise. I am doing my GCSE’s this year and I am very grateful. Also, just thinking ahead, I was wondering if you are planning on ever making A level content videos as they would be a great aid in mine and I’m sure many other student’s learning journeys.
Overall, I just wanted to give thanks for all the effort you put into your videos. 🎉
