Brown's School Science Revision Notes and Quizzes Website
WEBSITE HOMEPAGE of Dr Phil Brown GRIC, PhD Chemistry - INDEX 'SITEMAP' Download a PDF file version of this main index page for ALL convenient science links This PDF file essentially acts as an App file and all the www links should work. Download the PDF file to desktop, [my files], [cloud] etc. etc. The [SEARCH] box does NOT work from the pdf file, only on the xxx.htm web pages. DISCLAIMER: I do my very best to check all my writing, but I am not perfect and there may be a very tiny chance of an error or a 'silly' typo. If you think something is wrong, email chem55555@hotmail.com immediately and I will immediately rectify any error. I am NOT responsible for your exam grade, but I hope my science website helps you and good fortune in your studies. BUT, I do my best: The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires. Quote from William Arthur Ward "Thinking minds" Scroll down to find your academic level and science based course 1.
