The 2022 Paper 1 is rated as moderate to challenging (3.3/5). While Section A(1) and A(2) closely followed established past paper patterns, Section B featured several heavy algebraic and conceptual hurdles, particularly in Question 18 (3D Trigonometry) and Question 19 (Coordinate
The 2022 Paper 1 is rated as moderate to challenging (3.3/5).
While Section A(1) and A(2) closely followed established past paper patterns, Section B featured several heavy algebraic and conceptual hurdles, particularly in Question 18 (3D Trigonometry) and Question 19 (Coordinate Geometry of Circles).
These questions required strong spatial visualization and algebraic manipulation skills under tight time constraints.

The 2022 Paper 1 is rated as moderate to challenging (3.3/5). While Section A(1) and A(2) closely followed established past paper patterns, Section B featured several heavy algebraic and conceptual hurdles, particularly in Question 18 (3D Trigonometry) and Question 19 (Coordinate Geometry of Circles). These questions required strong spatial visualization and algebraic manipulation skills under tight time constraints.
Where the Marks Are
Section A represents a crucial harbor of marks, comprising 70 out of the 105 total marks. Standard topics such as Polynomials (Q4, Q14), Variations (Q10), and Measures of Dispersion (Q9, Q11) offered straightforward marks for candidates who had done thorough past paper drillings. Section B’s Q15 (Probability) and Q16 (Completing the Square) were also relatively friendly entry-level Section B questions.
