Braille letters and numbers are read from six-dot cells arranged in two columns and three rows. Each raised-dot pattern represents a character, so dot position matters as much as the number of raised dots. The letter A is dot 1, B is dots 1-2, and C is dots 1-4.

Visual Braille drills help learners build pattern recognition before moving to tactile reading, contractions, punctuation, or full words. Digits add one more rule: the number sign, dots 3-4-5-6, appears before the letter-style patterns for 1 through 0.

A multiple-choice score is useful, but it should be read narrowly. It measures recognition of displayed cells under the selected quiz settings. It does not prove tactile reading speed, contraction knowledge, punctuation knowledge, or real-world Braille fluency.

How to Use This Tool:

Choose the practice pool and question count before starting the run.

Set Quiz set to Letters (A-Z), Numbers (0-9), or Letters + Numbers (A-Z, 0-9). The setup text shows the current pool size.
Choose Number of questions. Letter runs support 5, 10, 15, 20, or 26 questions; number runs support 5 or 10; mixed runs support 10, 15, 20, 30, or 36.
Open Advanced only when you want a repeatable run. Enter Random seed to replay the same question order and answer ordering later.
Select Start Quiz. Each prompt shows a Braille cell image and four answer choices.
Choose the answer that matches the displayed cell. After answering, use Next until the score summary appears.
Open Attempt Ledger to compare Your answer and Correct answer. Use Accuracy Split Chart for the correct-versus-wrong balance, and Retake (same seed) when you want exact replay.

Interpreting Results:

Primary score is the count of correct answers over total questions, and Correct % is the rounded percentage. Always read those values with the selected set, question count, and seed. A perfect 5-question letter run is not the same evidence as a perfect 36-question mixed run.

The Attempt Ledger is the most useful study output because it shows each displayed cell, your answer, the correct answer, and whether the row was correct. Repeated misses often point to a dot-position confusion, such as mixing dots 1-2 with dots 1-4, or forgetting that digits are introduced by the number sign.

Do not overread a high score as tactile fluency. Use tactile materials, contractions, punctuation practice, and reading-speed exercises separately before judging full Braille skill.

Technical Details:

A six-dot Braille cell has positions 1, 2, and 3 down the left column, and 4, 5, and 6 down the right column. The quiz uses uncontracted letter patterns for A through Z and digit patterns that reuse A through J after a number sign.

Because the quiz is visual, the dot image is a prompt for recognition rather than an embossed tactile sample. It is accurate for dot-position study, but tactile reading also depends on physical dot size, spacing, hand movement, and context.

Lookup Core:

U	1-3-6	V	1-2-3-6	W	2-4-5-6	X	1-3-4-6
Y	1-3-4-5-6	Z	1-3-5-6	Digits use number sign dots 3-4-5-6 plus A-J patterns.

Braille number patterns used by the quiz
Digit	Cell Pattern	Digit	Cell Pattern	Digit	Cell Pattern
1	number sign + A	2	number sign + B	3	number sign + C
4	number sign + D	5	number sign + E	6	number sign + F
7	number sign + G	8	number sign + H	9	number sign + I
0	number sign + J	The number sign is dots 3-4-5-6.

Formula Core:

Each prompt contributes one point when the selected answer matches the correct cell. The chart uses the same raw score and total question count as the summary.

\begin{matrix} S & = & \sum_{i = 1}^{n} c_{i} \\ P & = & round (\frac{S}{n} \times 100) \\ W & = & 100 - P \end{matrix}

Braille quiz scoring symbol meanings
Symbol	Meaning
`n`	Total questions in the run.
`c_i`	One when question `i` is correct, otherwise zero.
`S`	Raw score shown as correct answers over total questions.
`P`	Correct percentage, rounded to a whole percent.
`W`	Wrong percentage, calculated as the remainder from 100 percent.

Quiz Construction:

A seeded run is repeatable. The selected pool is shuffled, the requested number of prompts is taken from that pool, and each prompt receives three wrong options from the same pool when enough alternatives exist. The answer choices are shuffled too, so the seed controls both question order and correct button position.

Worked Examples:

Short letters practice

A learner chooses Letters (A-Z), sets Number of questions to 10, and leaves Random seed blank. A finished Primary score of 8/10 with misses on B and C points to a dots 1-2 versus dots 1-4 confusion.

Repeatable number drill

An instructor chooses Numbers (0-9), sets 10 questions, and enters the seed numbers-week-1. Every learner receives the same digit prompts and answer ordering, so comparing Attempt Ledger rows is fair across the class.

Mixed review before tactile work

A mixed 36-question run gives full coverage of the built-in letters and digits. A score of 30/36 is useful, but rows involving digits should be read with the number-sign rule in mind before switching to tactile reading practice.

FAQ:

Does this teach contracted Braille?

No. The quiz focuses on uncontracted letters A-Z and digits 0-9. It does not score contractions, punctuation, capitalization indicators, whole words, or tactile reading speed.

Why do numbers show two cells?

Digits are shown with the number sign, dots 3-4-5-6, followed by the letter-style patterns for A through J. That makes Numbers (0-9) different from letters-only practice.

What does the seed change?

The same quiz set, question count, and seed rebuild the same prompts and answer ordering. Use Retake (same seed) for exact replay or leave the seed blank for a fresh run.

Why did my question count change?

The count is limited to values allowed by the selected pool, so a shared or pasted count can be moved to the nearest valid option for that set.

Glossary:

Braille cell: A six-dot position grid used for one Braille character or indicator.
Dot position: The numbered place of a raised dot within the cell, from 1 to 6.
Number sign: The dots 3-4-5-6 indicator that marks following A-J patterns as digits.
Attempt Ledger: The result table that compares each chosen answer with the correct answer.
Seed: Text used to replay the same shuffled quiz run.
