Grading on this platform: start at 0; Q1–15 award 2 points each and Q16–25 award 4 points each; wrong or blank answers score 0; maximum 70. Official SASMO reference rules: start at 15; Section A +2/−1/0 for correct/wrong/blank; Section B +4/0/0; maximum 85. The supplied volume prints the section rates and maximum 85, but does not explicitly print the initial 15; that baseline comes from the official format reference.
