About TeachAllAboutIt

TeachAllAboutIt was founded in 2017 by Holly Billinghurst, a Computer Science teacher who now supports students full time through tuition and digital resources. This site has been developed over a number of years to be used as a digital text book for GCSE & A Level Computer Science students.

With our online computer science resources now used in a number of schools in the UK and worldwide, the tuition & teacher CPD area of TeachAllAboutIt has been moved to its own website.

We firmly believe that given the correct resources, all students can make excellent progress in computer science and enjoy it at the same time. Our resources aim to support students studying in traditional classrooms as well as those who are home educated or studying remotely.

Our computer science pages include topic introductions for everyone with additional material & resources for subscribers to cut out the pain for revision.

Resources cover: CIE, OCR, and AQA for GCSE & A Level GCSE Computer Science Revision.

Educators can also benefit from access to classroom resources and CPD online or in person.
