If 3x + 7 = 22, what is the value of 6x + 5?
Chapter 01 · The learning loop
Check one answer, understand the route, meet it again later, then start the next useful set. Each result has a useful next step.
Answer → understand → reviewSample learning trail · Algebra
01 · Answer checked
If 3(x + 2) = 21, what is x? The sample answer chose 7 after dividing by 3, but before subtracting 2.
02 · Worked route
Keep: continue until the variable is alone.
03 · Spaced return
A short, similar question returns when recalling the route takes effort—not immediately while the steps are still on screen.
04 · Clear next move
The trail becomes one small assignment, based on the step that needs another pass.
Chapter 02 · Test-day rhythm
Rehearse a full-length, timed adaptive format until answering, flagging, and reviewing feel routine—so your attention stays on the question.

Researchers studying urban tree cover found that neighborhoods with older canopies cooled more slowly after sunset, preserving a measurable temperature difference into the night.
Chapter 03 · Five-question duel
Challenge an accepted friend to five practice questions. Correct answers score; quicker answers earn more.
3(x + 4) − 2x = 3x + 12 − 2x = x + 12.

Chapter 09 · Straight answers
The useful boundaries, in plain language—what stays free, what is original, what is available, and what this page illustrates.
Core practice, worked explanations, mistake review, practice tests, score history, and basic progress stay free—with no trial or card required. Advanced coach-level analysis, such as detailed timing or skill breakdowns, may be Pro later.
No. FullPrep uses original, unofficial practice content and is independent of the College Board. The test flow is Bluebook-familiar—timed modules, flagging, review, and an adaptive second module—but Bluebook remains the official test-day practice source.
You can challenge an accepted friend to a five-question duel. The replay on this page is a simplified demo against a simulated rival, with no real opponent or account rewards.
Yes. Guilds have a weekly goal of 50 eligible practice attempts. Each member’s first practice attempt on a question per UTC day can count, and completion awards contributing members 100 XP. Names and progress on this page are illustrative examples.
No. A correct first practice attempt on a question each UTC day earns two study dust toward cosmetic cat cards and crates. Repeats that day earn no dust. Cat cards are not sold for real money and never change questions, scores, or gameplay power.
New accounts appear on the leaderboard by default. Turn visibility off in Settings to hide your board entry and XP/level from other students. Your public profile can still show streaks, counts, and accuracy; enable Private profile to hide those study stats too.
