Thanks. We'll cover the exam-based (external) units first, as they're more complicated. The table below (from
the specification) shows the minimum points you get for each such unit, depending on the grade and unit size (in GLH, guided learning hours).

However, as it says in the various grade boundaries documents, "Points are awarded on a
sliding scale between the grade boundaries based on the number of raw marks achieved by each learner". This is why I wanted to know when you'd taken the exams, and hence what the grade boundaries were.
January 2024The January 2024 grade boundaries, extracted from
here), are below.

For
Unit 1, a 90 GLH unit, you obtained 43 marks out of 90. That reached the threshold for a Merit (which was 41 marks) and was 2 marks into the 18 marks (59 - 41) covered by that grade. So you get 15 points for the Merit, plus 2/18ths of the additional 9 marks which a Distinction would have earned you. So you get
16 points.
For
Unit 3, a 120 GLH unit, you obtained 38 marks out of 60. That reached the threshold for a Merit (which was 30 marks), and was 8 marks into the 12 marks (42 - 30) covered by that grade. So you get 20 points for the Merit, plus 8/12ths of additional 12 marks which a Distinction would have earned you. So you get
28 points.
January 2025The January 2025 grade boundaries, extracted from
here) are below:

For
Unit 5, a 120 GLH unit, you obtained 63 marks out of 120. That reached the threshold for a Merit (which was 53 marks) and was 10 marks into the 25 marks (78 - 53) covered by that grade. So you get 20 points for the Merit, plus 10/25ths of additional 12 marks which a Distinction would have earned you. So you get
25 points (rounded).
For
Unit 7, a 120 GLH unit, you obtained 24 marks out of 50. This is right on the Merit boundary, so you get
20 points.
We then just have to plus those numbers, and the grades for you internal (coursework-based) units unto the official Pearson grade calculator to see that you have a total of
212 points, for an overall grade of
DDM.

Please check the maths above. It easy, but also easy to make a silly mistake.
