Sure. As you sat those exams at different times, meaning we'll need to reference different grade boundaries, I'll do each unit separately. All three units are 120 GLH (guided learning hours) so we'll be referencing the right column of this table (from
the specification) throughout:
Unit 1 - Engineering Principles - June 2024 - 29 marks (pass)The relevant grade boundaries, from
Grade boundaries - June 2024 - BTEC Nationals, are:

The difference between the M and P boundaries is 42 - 19 = 23 marks. You achieved 29 - 19 = 10 marks over the P boundary. So you earn the points for a P plus 10/23rds of the points difference between a P and an M. That points difference is 20 - 12 = 8. So you earn 12 + (10/23rds of 8) =
15 points (rounded).
Unit 3 - Engineering Product Design and Manufacture - January 2024 - 29 marks (pass)The relevant grade boundaries, from
Grade boundaries - January 2024 - BTEC Nationals, are:

The difference between the M and P boundaries is 32 - 21 = 11 marks. You achieved 29 - 21 = 8 marks over the P boundary. So you earn the points for a P plus 8/11ths of the points difference between a P and an M. That points difference is 20 - 12 = 8. So you earn 12 + (8/11ths of 8) =
18 points.
Unit 6 - Microcontroller Systems for Engineers - January 2025 - 45 marks (merit)The relevant grade boundaries, from
Grade boundaries - January 2025 - BTEC Nationals, are:

The difference between the D and M boundaries is 52 - 37 = 15 marks. You achieved 45 - 37 = 8 marks over the M boundary. So you earn the points for an M plus 8/15ths of the points difference between an M and a D. That points difference is 32 - 20 = 12. So you earn 20 + (8/15ths of 12) =
26 points.
CaveatsNote that I've rounded the calculated points in each case. Pearson don't specify exactly how they do this (they may always round up, or always round down), so I've made an assumption here. Also, the approach I've used is a simple extrapolation from the following statements, within both the specification and the grade boundaries document, respectively:
• "Raw marks from the external units will be awarded points based on performance in the assessment. The table below shows the
minimum number of points available for each grade in the external units."
• "
Points are awarded on a sliding scale between the grade boundaries based on the number of raw marks achieved by each learner."
Please check my maths. To err is human.
