Hi Cognito. I just wanna say that i found your channel recently and... ITS AMAZING! I have exams in two weeks (which are going to be used as evidence for my GCSE's) and I am a very visual learner. I had forgotten how useful videos are to me as a form of revision and this channel has made my revision so much easier - seriously saved my exams! Reading through notes and writing flashcards are just really passive for me and I constantly lose concentration. I love how your videos are short, information packed and engaging. I can't wait to use your website in the near future also! Thank you for making such a difference to my revision!

[@lilifabre]

Thank you for the video! One thing though: using this method, please make sure that write that you are multiplying by 100%, not just 100... Otherwise, you are writing that 12.5=0.125 etc.

[@ryancahill9265]

[@naliabellamy6580]

What if we only have the percentage of change and no original figure?

[@neolyramona2779]

You can not have percentage with out the original number I think 😅
