### GCSE Grades Old and New

How do they compare?

 New Grades Old Grades 9 A* 9 8 8 A 7 7 6 B 6 5 5 C 4 4 3 D 3 3

### GCSE Higher Tier Grade Boundaries

Higher Tier Grade Boundaries (out of 240 possible marks):

 Sitting Grade 9 Grade 8 Grade 7 Grade 6 Grade 5 Grade 4 Grade 3 Jun 2017 190 157 124 96 68 41 27 Nov 2017 189 150 112 85 58 32 19 Jun 2018 202 170 139 109 79 50 35 Nov 2018 194 159 125 95 66 37 22 Jun 2019 198 167 137 108 80 52 38 Nov 2019 197 165 133 103 73 43 28 Nov 2020 189 157 126 96 66 37 22 Average % 81% 67% 53% 41% 29% 17% 11%

These are the higher tier grade boundaries for all past sittings of the new Edexcel GCSE Maths. The first two sets of exams were not at all popular with students but the June 2018 exams were viewed as more reasonable. The grade boundaries were higher but students felt they had more opportunity to demonstrate their skills and knowledge. Grade boundaries for November exams are not as reliable as boundaries for June exams because there are far fewer students taking what essentially are re-sit exams.

All except the November 2020 exams were taken before the pandemic but give an indication of what you can expect both when completing past papers and when sitting your actual GCSE exams in May/June 2023.
