This is an absolutely fantastic resource! We have just started running the BTEC level 3 Applied Science this year so we are struggling a bit with getting hold of good quality resources! Your Unit 4 briefs are excellent! Do you have the practical sheets to go with them? I don't fancy reinventing the wheel if you can ping them across on an email! Email address is email@example.com
I can send you back some of the resources I have for Chemistry or KS3 if you need anything.
