The 'whole of the topic in … minutes' videos DO NOT comprehensively cover everything you need to know for your exams. It would be impossible to include 2 years of teaching in 1 hour. These should NOT be your only source of revision [ Ссылка ] My exam predictions are just GUESSES!! I don't have any insider knowledge just years of looking at exam papers.

Disclaimer; You should not carry out any of these practical’s without carrying out a full risk assessment of your own first.

I am human, and I make mistakes, please point out any that you find and there is no need to follow that with a load of abuse.

TuitionKit allows you to schedule your revision videos, mine and loads of other great YouTubers! [ Ссылка ]
