OCR Advanced Subsidiary GCE in Physics A (H158)

OCR AS Physics A both extends prior learning (motion, circuit electricity) to a greater depth of understanding and also introduces new physics (waves, quantum mechanics) to give a flavour of where further study might lead. It also develops all-important practical skills in the areas of recording and analysing data, evaluating the accuracy and reliability of that data and the conclusions drawn from it, and recognising areas where experimental technique is flawed and improvements are possible.


See the G481 Mechanics and G482 Electrons, Waves and Photons pages.

Practical skills

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 G483 Practical Skills in Physics 1 for more details.


H158 is composed of three assessments:

  • G481 Mechanics
    • worth 30% of the course credit
    • assessed by a 1hr exam (60 raw marks, 90 UMS)

You can be entered for the exams in January or in May/June.

Grades available

Grades obtainable run from A to E. Your overall grade is decided by the number of uniform marks you attain over the three assessed units:

Grade A B C D E U
UMS 300-240 239-210 209-180 179-150 149-120 119-0

"U" means "unclassified" and is not certificated.
