Know exactly what
to study next.
Start with a diagnostic. Get a plan built around your test date and the hours you actually have. Then practice the specific skills you miss — with explanations that tell you why the wrong answer looked right.

How it works
Three steps, then repetition.
There is no trick to this. Measure where you are, work the plan, and check the measurement again.
- 1
Take a diagnostic
One full-length test, scored by skill rather than by section. It takes about two hours and it is free.

Practice what you miss
Every answer updates the estimate for that skill, so the next set is drawn from wherever you are weakest.

Practice
The workspace, not a screenshot of one.
Highlighting, answer elimination, mark for review, and a calculator on Math — the tools you would actually use on test day. Try them here.
Sample passage
When mycologist Dara Ibeh first proposed that certain fungi transport nutrients between unrelated trees, few colleagues took the claim seriously. Over the following decade, however, three research groups working on separate continents reported the same pattern in their own field sites. Ibeh's hypothesis was ______ by evidence she had never collected herself.
Which choice completes the text with the most logical and precise word or phrase?
Original sample question written for Bliss prep. Not official College Board material.
What you get
Four things that move a score.
Practice volume alone does not raise a score. Understanding a miss, getting unstuck, sitting a full test, and coming back to the same question a week later — those do.
Explanations
Every wrong answer gets its own explanation.
Knowing the right answer teaches you very little. Knowing why the choice you picked was designed to look right is what stops you picking it again.
- A one-line answer you can read in ten seconds
- Step-by-step working behind a disclosure
- A separate reason each distractor fails
A jacket's price is reduced by 30%, then by a further 20%. The final price is what percent less than the original?
Why B fails
This adds the two percentages. The second discount applies to the already-reduced price, not to the original.
AI tutor
A tutor that makes you find the step.
It sees the question, your answer, and how long you spent. It starts with a hint and only works toward the answer if you are still stuck.
- Hints before answers, always
- Explains why your specific choice failed
- Generates a similar problem to test the fix

AI responses can be wrong. Check them against the written explanation.
Practice tests
Full length, properly timed, two modules per section.
Four modules, a break screen, module instructions, and a second module that adjusts to how the first one went. Sit it once a fortnight and the predicted score becomes worth reading.
- Reading and Writing, then Math — two modules each
- Correctness stays hidden until the module is submitted
- Timing analysis by difficulty when you finish

Mistake review
The queue that does the actual work.
Missed, guessed, marked, or answered correctly but far too slowly — all of it lands in one queue with a spaced schedule, so you meet the question again before you forget it.
- Filters by subject, skill, difficulty, and status
- New, Learning, Review soon, Mastered

Analytics
Charts that end in a decision.
Every visualization here answers one question: what should I practice next? Anything that could not answer it was cut.
Illustrative exampleSample figures shown to illustrate the interface. They are not real student results.
Predicted score
Unofficial estimate, weighted by question difficulty.
Predicted composite score rose from 1090 at the diagnostic to 1200 today, with practice tests at 1140 and 1190 along the way.
Accuracy by domain
Where the next hour of practice is worth most.
Standard English Conventions is strongest at 84 percent. Advanced Math is weakest at 57 percent, followed by Expression of Ideas at 59 percent and Algebra at 62 percent.
Questions per day
Consistency matters more than any single long session.
Over the last fourteen days the student practiced on ten of them, ranging from six to thirty-two questions a day, with four rest days.
Average time by difficulty
Fast and wrong is a different problem from slow and right.
Easy questions average 48 seconds at 82 percent accuracy, medium 79 seconds at 66 percent, and hard 118 seconds at 47 percent.
What this student should do next
Advanced Math is the weakest domain and hard questions are taking almost two minutes. Two 20-minute nonlinear-equation drills this week, untimed first, then timed.
Staying with it
Enough motivation to keep showing up.
A streak, a level, and a weekly goal. No leaderboards for minors by default, and no messages that punish you for missing a day.

1050–11001250–1300The mistake queue was the part that changed things. I stopped re-reading notes and started re-answering the exact questions I got wrong.

1200–12501350–1400I could see that my accuracy was fine and my pacing wasn't. Two weeks of timed sets fixed a problem I didn't know I had.

Questions
The things students ask first.
If something here is not covered, the answer is probably in the app itself — every score estimate links to how it was calculated.

The diagnostic takes about two hours and costs nothing. You will finish it with a score estimate and a week of specific work.
