Here is another interactive replay video to help you revise for GCSE science exams.
Use the bookmarks to skip to points in the video when I cover specific ideas.
The small dots on the video timeline are where the video will pause and an interactive question will pop up for you to answer which will test your understanding and recall.
Please watch this space for more such videos, and if you’re interested in taking part in the upcoming webinars please book tickets by logging in and selecting the webinars from our calendar.
I hope you find them useful, and good luck with your exams!
