Questions Covered in This Set
10 cards to master
What pacing target does this lesson use for a timed set?
8 questions in 11 minutes — about 80 seconds per question, close to real PSAT pacing.
What should you do if a question stalls you at 90 seconds?
Mark it, guess, and move on. Finishing the set matters more than winning one battle.
Why circle questions where you hesitate more than ~20 seconds?
The hesitation is data about weak skills, even when you get the question right.
What two things do you write for each answer during a set?
The answer plus a one-word method tag: solve, backsolve, plug-in, graph, or guess.
Shortcut: sum of the solutions of x² − 7x + 10 = 0?
Sum of roots = −b/a = 7 — no factoring needed.
When is substitution faster than elimination in a system?
When one variable is already isolated (e.g., y = 2x).
How do you find k so that 4x + ky = 9 is parallel to y = −2x + 1?
Rewrite as y = (−4/k)x + 9/k; set −4/k = −2, so k = 2.
Solve |2x − 5| = 9 and give the positive difference of solutions.
x = 7 and x = −2, so the difference is 9.
Solve −4 < 2n + 2 ≤ 10 for the greatest integer n.
−6 < 2n ≤ 8 → −3 < n ≤ 4, so the greatest integer is 4.
What is the most common source of 'careless' errors?
Answering the wrong question — solving for x when the problem wants 2x, or finding y instead of x.
