I'm planning on taking WJEC Biology, Chemistry and Physics next year for A level. Can anyone recommend any good textbooks, YouTube videos or other revision resources? I've been trying to find something, but I'm finding it hard to find resources for the new specification.
Also, are the WJEC endorsed books for these subjects any good? I've looked at the reviews and they don't seem great. Are they essential reading for taking these subjects?
And actually passed?
