To support your students in catching up with their course, the ‘Bridge the gap’ series is a sequence of courses, aimed at consolidating knowledge, whilst also looking forward to assessment at the end of 2021. This short course will focus and reacquaint students on key first year topic of Waves in the first year programme of most A level Physics syllabuses which many students will be studying during the summer term 2020. The webinar will focus on the key challenges of the interference of waves and refraction of light and address qualitative and problem-solving questions that are likely to be asked on these topics. The webinar is interactive, there will be tasks, activities, work set, opportunities for students to ask questions throughout. There will also be course notes for the students produced by current examiners in A level Physics.


  • Provide a deepening of knowledge and skills of first year topics as a bridge towards the second year of you’re a level Physics studies
  • Experience a unique opportunity to hear from an experienced examiner in A level Physics
  • Gain top level advice and guidance on how to access the higher grades in examinations
  • Enhance your understanding of key areas of Physics, all linked directly to the exam papers
  • Take away a full set of conference notes, with examination tips and example answers
