Since 2017, GCSE results have been given grades from 9-1, enabling more grades to be awarded than the former A-G lettering, which is still used for A-levels.

One week after A-level results were announced across England, Wales, and Northern Ireland, students will be picking up their GCSE grades from 8am on Thursday, August 20, with the grades determining places in sixth forms, colleges and potentially future employment.

Once the results have been picked up, students can enjoy some tasty discounts at scores of restaurants and pubs.

Here is how the numbers relate to the old letter system.

GCSE grades explained

How does the numbered system compare to the old lettered system?

The number scale is not directly equivalent to the old letter one, but there are comparison points:

  • The bottom of grade 7 is comparable to the bottom of the old grade A,
  • The bottom of grade 4 is comparable to the bottom of the old grade C,
  • The bottom of grade 1 is comparable to the bottom of the old grade G.

Grade 4 has effectively replaced C as the metric for a good pass, while the Department for Education has said that a grade 3 is the minimum for mathematics and English to continue in education without a resit.
