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.
AQA students can buy the book from Amazon (links below) students sitting other exam boards can get a free ‘top up’ ebook from my website www.primroseki...
Combined Science required practical book geni.us/DOshu
Biology required practical book geni.us/2aGmjIL
Chemistry required practical book geni.us/lepsNQ
Physics required practical book geni.us/oeQPxAO
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.

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 • Do the 'whole topic in... 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.

this is helping me a lot but I'm really struggling to hear you sometimes
that's ok :) thank you for making this series it really helped me with my exam today
bro just turn on the volume
You didn't miss much. She was randomly using the wrong chemical names half the time, and was pointing out the colors about as good as anyone who can see would.
These videos have been helping me to revise for my chemistry exams, they are really useful and informative and also much less boring than using a revision guide! In particular this video has helped me because we never got to do these tests in school so i didnt get to see the colour changes. so Thank you!!
Iron 2 is green iron 3 is brown
A little slip of the tongue! you said add sulphuric acid to the test tube instead of sodium hydroxide.(at 3.02). Also better to say aluminium ions, magnesium ion etc and not aluminium, magnesium etc.
thank you this was a very informative video :)
this video is really very nice

You can see by the scratch marks on her hand that she likely has a cat or a dog.
Edit: Ok, I just looked at the channel icon and realised she DEFINITELY has a cat. (Yes, I’m pretty dumb.)
