Year 11 Math Practice Questions and Topics

Year 11 (ages 15–16) is GCSE exam year, and the content — quadratics, simultaneous equations, surds and indices, trigonometry, circle geometry, graphs, sequences, probability, vectors and statistics — is largely a continuation and deepening of Year 10's syllabus rather than substantial new material. The shift in Year 11 is less about new topics and more about combining them: exam questions increasingly require using two or three skills together in one problem, working with surds (roots that don't simplify to whole numbers) alongside indices, and applying circle theorems that build on Year 10's basic circle work.

By the end of Year 11, a student should simplify expressions involving surds, apply circle theorems to find missing angles, solve harder simultaneous equations (including one linear and one quadratic), use vectors to describe movement or position, and interpret more complex statistical data, including cumulative frequency and box plots.

The most common difficulty is genuinely exam technique rather than new content: students often know the required method for a topic in isolation but struggle to recognise which method a multi-part, worded exam question is actually asking for, especially when a question doesn't name the topic directly. Circle theorems are a specific recurring sticking point — there are several distinct rules (angles in a semicircle, angle at the centre, alternate segment, and others) and mixing them up under exam pressure is extremely common, usually because they were learned as a list rather than practised on enough varied diagrams.

Year 11 is the culmination of the two-year GCSE course, and how a student performs directly determines their options at Sixth Form or College — a strong GCSE grade is generally the entry requirement for A-level Maths, so this year's revision quality matters more than any single topic within it.

The single most useful thing a parent can do this year is past-paper practice under timed, realistic conditions, followed by genuinely reviewing what went wrong rather than just checking the score — most Year 11 students already know the individual methods; what separates strong results is speed, accuracy under pressure, and recognising which method to use without being told. Little and often, spread across the year rather than crammed at the end, consistently produces better results than intensive last-minute revision alone.

Y11m Quadratics

Y11m Quadratics — question 1Normal

Factorise x² + 9x + 20.

  • (x + 4)(x + 5)✓ Correct
  • (x + 1)(x + 20)
  • (x + 3)(x + 6)
  • (x + 2)(x + 10)

Why: 4 and 5 multiply to 20 and add to 9.

Y11m Quadratics — question 2Average

Factorise x² − 25.

  • x(x − 25)
  • (x + 5)(x − 5)✓ Correct
  • (x + 25)(x − 1)
  • (x − 5)(x − 5)

Why: This is the difference of two squares.

Y11m Quadratics — question 3Good

Factorise 2x² + 7x + 3.

  • (2x + 1)(x + 3)✓ Correct
  • (x + 7)(2x + 3)
  • (2x + 3)(x + 1)
  • (2x + 7)(x + 3)

Why: Expanding gives 2x² + 6x + x + 3.

Y11m Quadratics — question 4Expert

Solve 3x² − 12 = 0.

  • x = 2 only
  • x = ±4
  • x = ±2✓ Correct
  • x = ±12

Why: 3x² = 12, so x² = 4 and x = ±2.

Y11m Simultaneous

Y11m Simultaneous — question 1Normal

Solve x + y = 10 and x − y = 4. Find x.

  • 5
  • 14
  • 6
  • 7✓ Correct

Why: Adding gives 2x = 14, so x = 7.

Y11m Simultaneous — question 2Average

Solve 3x + 2y = 16 and x − 2y = 0. Find x.

  • 8
  • 6
  • 4✓ Correct
  • 2

Why: Adding gives 4x = 16, so x = 4.

Y11m Simultaneous — question 3Good

Solve 4x + y = 17 and 2x + y = 11. Find x.

  • 5
  • 6
  • 2
  • 3✓ Correct

Why: Subtracting gives 2x = 6, so x = 3.

Y11m Simultaneous — question 4Expert

Solve 5x + 3y = 29 and 2x − y = 5. Find y.

  • 4
  • 3✓ Correct
  • 2
  • 5

Why: From the second, y = 2x − 5. Substituting: 5x + 6x − 15 = 29, so 11x = 44, x = 4 and y = 3.

Y11m Surds Indices

Y11m Surds Indices — question 1Normal

Simplify √16.

  • 4✓ Correct
  • 16
  • 2
  • 8

Why: 4 × 4 = 16.

Y11m Surds Indices — question 2Average

Simplify √50.

  • 2√5
  • 10√5
  • 5√2✓ Correct
  • 25√2

Why: √50 = √25 × √2 = 5√2.

Y11m Surds Indices — question 3Good

Simplify √12 + √27.

  • 5√6
  • 6√3
  • √39
  • 5√3✓ Correct

Why: 2√3 + 3√3 = 5√3.

Simplify (3 + √5)(3 − √5).

  • 5
  • 4✓ Correct
  • 14
  • 9

Why: This is a difference of two squares: 9 − 5 = 4.
