Level 4 - Math & Problem Solving

Our Level 4 Math & Problem Solving course targets students in Grades 8 to 10. This level addresses difficult topics in math and applies advanced problem-solving strategies.

Level 4 instruction includes, but is not limited to:

  • Exponents and radicals
  • Polynomials
  • Linear equations and systems of linear equations
  • Quadratic equations
  • Problem solving for linear equations, systems of equations, and for quadratic equations
  • Geometry on a plane (axioms, theorems proof, problem solving)
  • Introduction to trigonometry: trigo ratios, solving identities, sin and cosine laws, problem solving
  • Arithmetic and geometric sets and series
  • Mathematical induction
  • Fundamental law of combinatorics, permutations, and combinations
  • Logic problems – higher level content (see Levels 1 – 3)
  • Brain teasers

Prerequisite for Level 4: Completion of Level 3 OR successful completion of assessment interview (for new students).

Sample problems

Given trapezoid ABCD. MN is a mid-line of ABCD. MN = 28cm.
Sides AB and CD continued until they meet in point P. image04APD = 30°.
A circle with diameter MN is drawn with the center O in
the middle of mid-line MN. Points B and C are on the circle.

  • Find length of AD.


Stephanie and Elizabeth live in houses on the same street. The street is straight and there is a very high transmission antenna between their houses. Stephanie observes from her house the top of the antenna at the angle of elevation 33°, but Elizabeth observes from her house the top of the antenna at the angle of elevation 47°. How high is the top of the antenna from the ground, if Elizabeth’s house is 120 meters nearer to the antenna than Stephanie’s house?
