my school gives these books out. i never really used it for the activities, just scribbled answers when my teacher was checking coursework, haha. it has activities for research methods which i did properly in anticipation for the unit 4 exam

i think these activities were beneficial in understanding and
applying knowledge.
the practice tests in it are pretty useless though i thought
i never filled in the glossary, i just used it as a checklist to make sure i understood the terms
it has LOADS of revision questions on each area of study which i found very helpful though for writing up thorough notes and exposing my areas of weaknesses. i never had any checkpoints or any of those things and i found the revision Qs to be more than adequate, but i'd personally buy this workbook
