The Bizstim Library is open. It is a shelf of ready-made question banks you can copy straight into your own account, and the first bank on it is TACHS: 1,128 practice questions with written explanations, difficulty tags, and drawn figures.
What Is In The Bank
1,128 multiple-choice questions across three TACHS sections: Reading (306), Written Expression (282), and Math (540). Every question carries a written explanation, so a wrong answer teaches something on the spot. Every question also carries a difficulty tag of Low, Medium, or High, and a topic type. There are 64 types in all, from Context Clues and Subject-Verb Agreement to Coordinate Plane and Slope, so a report can point at a topic rather than a score. Twenty questions carry a drawn figure that reads correctly in both the light and dark themes and enlarges on a click.

Import It In One Click
Open Question Banks and click Bizstim Library. The TACHS card shows the question count and the sections it covers. One click copies the whole bank into your account: questions, choices, explanations, difficulty tags, types, and figures. From that moment it is your bank. Edit a question, add your own, or deactivate what you do not want, and your copy is yours alone. The Bizstim Library is available on the Small Business and Enterprise plans.
Four Ways To Practice
A TACHS Smart Event puts four practice strategies in the Implementing column, each one drawing from the TACHS banks attached to that event:
- TACHS Practice Questions. Instant feedback on every answer, and a summary by section at the end of each set.
- Timed Section Drills. One section against the clock, on a server-side timer, with answers advancing automatically so the pace is the point.
- Answer Elimination. Cross out the choices you can rule out, then answer from what is left. If the crossed-out choice was the right one, it says so.
- Error Log Review. Missed and guessed questions come back until one is answered correctly without a guess, and then it leaves the log.

Set Size And Difficulty, Chosen Every Time
Before each set: 10, 25, 50, or 100 questions, and Mixed, Low, Medium, or High difficulty, with the number of questions waiting at each level printed on the chip. Unseen questions are served first, the three sections rotate through the set so none of them dominates, and a set larger than its matching pool simply serves what it has.
Every Answer Is Reported
The Review page shows first-try accuracy beside current accuracy, a score for every set, a scores-by-set chart, and a question-by-question grid of any past set with the explanation on each row. Accuracy by difficulty, timed pacing, and elimination stats appear as soon as there is data behind them. The Exam Reports page rolls the same numbers up across everyone practicing, and the whole report downloads as a PDF worth handing to a parent.

Your Own Banks Sit Beside It
The imported bank works alongside anything you build yourself. Question Banks takes a CSV import with a downloadable template, and a Smart Event draws from every active bank attached to it, so your own material and the TACHS bank can turn up in the same practice set.
