Evidence 1
The student separates useful quantities from background details.
Difficulty Practice Guide
This page shows what medium practice should demand for grade 12 convergence tests word problems. The goal is not a larger worksheet. The goal is to make the student's reasoning visible enough to choose the next better problem.
What Changes At This Difficulty
Student Work Signals
MathRoutine watches for whether the student understood the situation, wrote a useful setup, handled the calculation, and answered the exact question asked.
separate useful numbers from background details
complete a two-step setup
interpret the result with the correct unit
Medium Readiness
A difficulty page earns its place only when it tells parents and teachers what to look for at this exact level. For medium grade 12 convergence tests word problems, the attempt should show more than a final number.
Evidence 1
The student separates useful quantities from background details.
Evidence 2
The solution uses a planned two-step or three-step structure.
Evidence 3
Units, labels, or comparison language are interpreted after calculation.
Difficulty-Matched Examples
These examples are not meant to be the whole practice set. They show the kind of reasoning pressure medium work should create for grade 12 convergence tests word problems.
A power series has radius 5 around x = 1. One endpoint is an alternating p-series with p = 2, and the other is harmonic. What is the interval of convergence?
Reasoning strategy
Use the radius for the open interval, then test each endpoint separately.
Support cue
Make endpoint decisions separate from the ratio-test result.
Why This Matters
Basic gives repeated targeted practice. Pro becomes useful when the student needs help understanding wording, recovering the setup, or seeing the same misconception return across attempts.
Compare plansPlacement Decision
Move down
Move down if the student understands the math only after the wording is simplified.
Stay here
Stay here when the student solves correctly but still needs practice planning the sequence of steps.
Move up
Move to hard when the student can explain why each step is needed before calculating.
