Thanks a lot! I've been using your website for a year now and it is by far the best.

[@Cognitoedu]

Great to hear you're finding the website helpful 😊

[@INFINIT3Rxpct]

@@Cognitoedu Can you please make the practice questions and past papers on your website a lot harder, or provide harder alternatives because I find your videos packed with dense information that I find really helpful in difficult exams but the practice questions and past papers are relatively easy and I don't find them challenging. Thanks!

[@lucyclark.]

Thanks for the video. I really struggled with this topic and now find it much easier

i think you need an english teacher over maths.

[@Rubinkys]

@@jackzammit5792 Plenty of people type horrendously when texting, not like a YT comment section is formal or anything. Also, you forgot to capitalize your "I". If you want to judge someone at least do it correctly.
