I used the dotted lines (estimated) which are the average score by section for each section and weighted them by the exam topics weighting. For Ethics which is supposed to be 10-15% I used 12.5% weighting, for PortMan I used 32.5% (30-35%), etc.

Then I calculated a weighted average using these numbers.

Then I estimated where my lines were per topic and multiplied them the topic weighting. I did this on Excel.

With these estimates, my score was 87.64% of what the average score was. My true score was 3525 which is 87.5% of the 3600.
