Practicals are 15% of your exam grade, this could be the difference between a grade 4 and a grade 5 or the difference between grade 7 and grade 9. There isn’t a large amount of content but there are a lot of skills that can be tested, to help you with this I’ve made videos of all the practical and written a workbook full or exam style questions.

I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. Even if you don't want to study science or maths further, the grades you get now will open doors in the future.

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.

Hi, I am doing my GCSEs this year and i can't find this experiment in the CGP guide or in the practical book we were given in class. Is it one of the named required practicals? I am very confused as i do remember doing it in class a while back,
Thanks for your help :)
