Good forensic notes? Make them yourself - tailor it to your own needs.
I used the Excel Chemistry guide along with my textbook to get information on it - chucked in a few diagrams from Google or MS Paint and then I had a set of Forensic notes that were good enough for me.
Other people would go 'ewww' at my approach and prefer all pictures, others a big mindmap. Whatever works for you. Personally, I like walls of text.
