OCR A2 Physics A builds upon the work done at AS level, while also introducing students to the latest developments in physics. Newton's Laws are developed to include momentum, before forces themselves are generalised into abstract fields of force in order to understand gravitational, electric and magnetic interactions. Classical thermodynamic ideas lead to a greater understanding of heat and gases, while work already done on the newer quantum theory is added to through a study of nuclear and particle physics. GCSE ideas of the Big Bang theory are widened into an introduction to the ideas of cosmology and applications of physics in medicine are visited through a study of imagining techniques such as CT and MRI.
See the G484 The Newtonian World and G485 Fields, Particles and the Frontiers of Physics pages.
You will be assessed under three categories: Qualitative skills, Quantative skills and Evaluative skills. Each year, OCR release three practical tasks under each of these three categories (ie nine altogether). You have to attempt at least one from each category, but your teacher may encourage you to try all three. Your best mark in each category is submitted.
See G486 Practical Skills in Physics 2 for more details.
H558 is composed of three assessments:
- G484 The Newtonian World
- worth 15% of the course credit
- assessed by a 1hr15m exam (60 raw marks, 90 UMS)
- G485 Fields, Particles and the Frontiers of Physics
- worth 25% of the course credit
- assessed by a 2h00m exam (100 raw marks, 150 UMS)
- G486 Practical Skills in Physics 2
- worth 10% of the course credit
- assessed a 3 in-school practical "tasks" (40 raw marks, 60 UMS)
You can be entered for the exams in January or in May/June.
Grades obtainable run from A* to E. Your overall grade is decided by the number of uniform marks you attain over the six assessed units:
"U" means "unclassified" and is not certificated.
To be awarded an A*, you need to achieve a grade A on your full A Level qualification overall (ie above 480 UMS in total over all six units) and also gain at least 270 UMS out of the 300 UMS available from the three A2 units.
