Hiii! I’m a BSc Chemistry (Applied and Sustainable Chemistry) third-year undergrad. I study at Stellenbosch university. Here you’ll mainly find notes for my degree: chemistry, microbiology, biochemistry. I also did chemical engineering (I), so you’ll find some Eng math notes here too. And of course, some matric bio, English and Afrikaans notes as well to help you ace those finals! Thank you for your support ;)
