so, I'm taking higher chemistry in 6th year and I'm wondering whether I need to do any background reading of standard grade stuff. I did do standard grade and got a grade 1. but that was 2 years ago and I've completely forgotten everything. thanks
I'd recommend getting the how to pass books. They're pretty handy and get all the pastpapers you can. I can't comment on standard grade as I did Int2. My school didn't do standard grade when I was there.
Higher is an expansion of stuff from Standard Grade so most of it is re-capped. Technically some required stuff isn't taught in the Higher 'course' but teachers usually go over it anyway for those who've forgot. I'd just look over the basics like writing formulas and electron arrangements and stuff... nothing stopping you going back over it quickly if you do feel stuck or forget something you're doing in class anyway. Unit 1 of Higher is nice and easy to start off with.
