I've never been one to pass math ever but I recently got back my GCE N'Level Examination results and I thought I was going to fail since I only started studying last minute but to my shock I passed. I didn't pass with good grades but I still managed to pass and that's all I'm happy for. This channel really helped me understand math easily compared to when I studied in school. Thank you very much!

Honestly there are a lot of different revision channels with there respective learning patterns but the way cognito shows and explains the work for the specific video is great u can pause at any time to write notes tips and personal options down let alone the fact that cognito explains everything perfectly so that u can understand what u are trying to work out step by step is jsut perfect for all revisers well educated of not it’s perfect for everyone personally this channel is helping me a lot and by the looks of it this is 2 years old and still affective! So thank u I saw this in my maths book and thought I was going to suffer but not any more ✌🏽

Hi! I absolutely love your videos! Question - is there a video for solving simultaneous equations using substitution? One of your videos said that there's a video for that but you've got 2 graph videos linked to simultaneous equations and one video on elimination. Anyways, you don't realise how much this is helping us!

Hi, I hope you are having a great day. I was just wondering if you could possibly make videos related to history in the future, because you guys make such great videos which are easy to understand and filled with information, and a lot of people would probably like history videos. Also, when can we be expecting the math part on the website?
@jajalulujaju
@jajalulujaju 2 года назад
I think for history you just have to memorise like know the timings and what’s going on that time and also remember the answer structures.

@hadiqaa7336
@hadiqaa7336 Месяц назад
i think you mean what if the divided answer is a negative/decimal, which is fine. for example 5y = 66 we HAVE to find Y. So you HAVE to divide even if it’s not divisible by 5. so 5y = 66 = 66 divided by 5 = 13.2 Y = 13.2. this is a random example btw. sorry if u dont get it but yeah its ok if u have negatives or decimals, good luck!

@fraudulentminke_
@fraudulentminke_ 8 дней назад
it's subtracting, so what we're actually doing is y - -6y but since there are two subtract symbols, it turns into addition, so in the end you're doing y + 6y to get 7y I'm not the best at explaining and I'm assuming you were revising for GCSEs which have already passed, but oh well 😅
