For Maths, there were only 15 questions in 2014 and 2015. From 2016 to 2019, the number of questions gradually increased, reaching a peak of 40 questions in 2020. After 2020, the number of Maths questions stayed high, ranging from 34 to 39 questions each year until 2025.

• For English, the number of questions ranged between 25 and 32 each year. The highest number of questions, 32, was in 2014, and the lowest, 25, was in 2020. From 2021 to 2025, the number of English questions stabilized at 27-29 per year.
• For Reasoning, the number of questions started high in 2014 and 2015, with 33 to 35 questions. After 2017, the number of reasoning questions began to decline, with 15 questions in 2020. The lowest point was in 2023, with only 14 questions, followed by a slight increase to 16 questions in 2024 & 18 questions in 2025.
