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!
