IGCSE Economics (0455) grade boundary calculator

Up to June 2026, Paper 1 is out of 30 and Paper 2 is out of 90. Cambridge weights them to a total out of 150, in which Paper 1 counts for 45 marks and Paper 2 for 105, so Paper 1 is 30% of the grade and Paper 2 is 70%. After each exam series, Cambridge sets the minimum weighted mark for each grade, and those grade thresholds are what this calculator uses.

From 2027, Paper 1 has 40 marks and Paper 2 has 80 marks, and Cambridge's 2027 to 2029 syllabus keeps the weighting at 30% for Paper 1 and 70% for Paper 2. No 2027 thresholds exist yet, so the 2027 tab assumes a weighted total of 150 again and compares your mark with the 2020 to 2026 thresholds. Treat its grades as estimates.

Cambridge sets the thresholds after each series is marked, so they move with how hard that series' papers turned out to be. Across the papers in this calculator, the A* threshold ranged from 101 out of 150 in March 2022 to 130 in March 2026.

The last digit of the paper code on the front of your paper is the variant: 0455/12 and 0455/22 are variant 2. Every variant is listed in the table, and your school's exams office can confirm which one you will sit.

No. It shows what your marks would have earned across past exam series and papers. Your real grade depends on the thresholds Cambridge sets for your own series, which are published after results day.
