Problem Sets
Skill-specific problem sets are designed to help students identify and close specific skill gaps, rather than practicing everything at once.
Consider a student who takes a practice test and discover that they struggle with Words in Context. Instead of repeating full-length tests they are assigned targeted problem sets focused specifically on that skill. With dedicated practice, their performance in that area improves measurably and when she returns to a full test, the progress is clear.
This is the core idea behind skill-specific problem sets: targeted practice leads to faster, more measurable improvement.
What's in the library:
Content Type | Source | Volume |
|---|---|---|
Reading & Writing practice questions | EdisonOS subject experts | 1300+ questions |
Math practice questions | EdisonOS subject experts | 1000+ questions |
Assign problem sets immediately after a diagnostic test to give students a focused, structured path to improvement.
How Content Sources Work Together
The Practice tests and Problem sets are designed to complement each other:
Students take a practice test to identify weak domains & weak skills.
They are assigned skill-specific problem sets to target those areas.
They return to a full practice test to measure overall progress.
This cycle of assess → target → reassess is what makes the EdisonOS content library a complete preparation system, not just a question bank.
