Chemistry

Chemistry is a popular subject at Westminster Tutors and our students enjoy the intellectual challenges and stimulation it provides. Chemistry is the study of energy and matter, and how they change and interact with each other. It is also known as the “central science”, as it connects the other sciences together. In addition to our own equipment, our students are able to use the extensive laboratory facilities at David Game College for practical experiments.

Specification

Although we offer all exam boards as our courses are individually designed, our chosen specification is OCR Chemistry A (H032 and H432).
