The Raw Focus video series is designed to cover the high yield, key concepts around which many examination questions are structured. If you can reproduce these core ideas yourself then the rest of an answer will issue forth.

The videos will complement content covered in the podcast series and are also posted in the relevant audio section.

We are working to complete the key concept syllabus listed below. If there are any specific topics that you would like to see covered please get in touch via twitter, or message us at basicscienceclinic@gmail.com, and we will produce a personalised video.
