This NEW online student session is aimed at consolidating knowledge in preparation for successful assessment in summer 2021. The webinar will focus on the key challenges of the photoelectric effect and wave particle duality and address qualitative and problem-solving questions that are likely to be asked on these topics. The online course is interactive, with Q & A discussion time and opportunities for students to ask questions built in. There will also be one or two tasks.

Students will also receive valuable course notes written and produced by the session leader, a current examiner in A level Physics.


  • Give opportunity for students to hear key points and key messages direct from a current examiner
  • Take away a deepened knowledge and skills base of advice and guidance 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
