    Many thanks,

    I am so so glad to have found this website- it is absolutely amazing. I’ve never seen a revision site better than this- I love how everything covered on here is from the specification as well as all the videos, key term lists and printable revision guides. I just discovered this site and I have a practice test in December and the real exam in May so I am going to use this website a lot. Thank you so much for making it- It must have taken ages to make all the wonderful content !

    We have just found your blog this week. I wish I had found it last year when I was doing extended IGCSE sciences. I wish I had come across then as I only got a B for my externals. I was wondering if you have anything for or can recommend an such site for AS Biology. This a wonderful site and good luck to all those your hard work and dedication may help.

      Thank you for your kind words. I don’t teach A level any more but you could try, which looks pretty good for Edexcel.
