The Foundation paper was a mix of "filling in blanks", "tick box" questions and short response questions - all of the expected standard.
Last year's General paper came under fire for its structure, but this year's was more balanced, containing quite a few "fill in the blanks" style questions, which act as a good bridge between Foundation and General, says Mr Mason.
If a candidate had prepared well for Credit, the General paper should have been very straightforward and a "nice warm-up". Of the Credit paper, he said: "If there is one paper that has improved the most, it is the Credit one."
It had more Credit-level content than last year's, although, arguably, there is scope for yet more extended response questions - something Mr Mason expects will come in future years. Nevertheless, it did overcome the criticism of last year's Credit paper that it did not prepare candidates well for Higher.
