Digital SAT · Reading and Writing
A complete Reading and Writing course, built by language teachers and researchers. Every ranking in it is counted rather than assumed. Here is one of the findings.
The em dash is in play in roughly one question in nine and is correct in a quarter of those. It is not there to be chosen. It is there because it looks decisive.
01 · Lessons
Twenty-two lessons across Reading and Writing, each generated from the source chapter it teaches and paired with its own focused-practice drill. Overview first, then in-depth for the harder applications.

A conventions course for students whose grammar score will not move. Included with membership, and available on its own for $12 a month.
Standard English Conventions is 24.6% of the Reading and Writing section — about one question in four, 13 to 15 per test. We counted that across real practice modules rather than taking it from a syllabus. It is also the only quarter of the section whose rules are finite: reading comprehension improves slowly, conventions can be fixed in weeks. Students usually know the rules already. What they cannot do is name the thing that pulled them to the wrong choice — so that is what we teach.
One decision · 48% of the section
Almost all conventions punctuation is settled by a single question: is what stands on each side of the blank a complete sentence? An interactive trainer splits the sentence in two and asks about each side separately, so the decision is made on structure before any punctuation is offered.
| Sentence + Sentence | period · semicolon · comma + FANBOYS |
| Sentence + Fragment | colon · dash |
| Fragment + Sentence | comma, or nothing |
573 of 597 items
Not only the rule that decides the item, but the feature that made a wrong choice attractive. Write both down after a miss and the same mistake stops repeating.
Nine skills · four tiers
One rule in one short sentence first, then full SAT phrasing, then the cases that catch students who already know the rule.
Method
Every ranking on this site is measured rather than assumed. The figures are only useful once you know exactly what each one counts, so here they are.
A mark can be everywhere and still rarely be the answer. That gap is the definition of a decoy, and it is the most useful thing these figures tell a student. Where our own data contradicts a rule found in a standard reference, we report the rule and flag the item — the corpus supplies examples, not authority.
See the reasoning
A Reading and Writing item with the full reasoning attached — predict, eliminate, commit. This is what sits behind every question in the bank.
Which choice completes the text with the most logical and precise word?
While some dismissed her early findings as ______, later studies confirmed that Dr. Okafor's conclusions were remarkably well-supported.
Three moves decide this question. Tap through them — no memorising, just the read.
How the practice works
Adaptive
Sets keep returning the question families you miss, at intervals set by a spaced-repetition schedule rather than a fixed queue.
Coach
Once for the rule that decides the question, and once for the feature that made a wrong choice attractive. The second explanation is the one that changes scores.
Assessment
Complete Reading and Writing sections under real conditions, with item-level reporting afterwards.
Measurement
Reporting names which specific distractor pattern is costing you points, because “62% on conventions” tells a student nothing they can act on.
Who builds this
Everything here comes out of classroom work. The counting started because students who could recite the colon rule kept choosing colons after fragments, and no available book explained why. We record what learners actually do, publish the method alongside the findings, and correct the material when the evidence says we were wrong.
Membership
Some of this section has an end. Conventions is a fixed set of rules; transitions is six relationships and five traps; vocabulary is a list. Those you can finish. Reading comprehension is the part that needs months. Buy the part you actually need.
