Scoring a 1590 on the SAT meant Jai couldn't afford grammar mistakes on the Writing section, so he internalized the rules governing subject-verb agreement, parallelism, modifier placement, and comma usage at a granular level. He breaks grammar down into a decision tree: a small set of patterns that ...

As one of the first freshmen accepted into Penn's certified writing tutor program, Jessica spent years giving detailed feedback on sentence structure, punctuation, and usage. She unpacks grammar rules — subject-verb agreement, comma splices, dangling modifiers — by showing students how each rule sha...

Kate treats grammar as a logical system rather than a list of arbitrary rules, breaking down sentence structure the way an engineer might break down a schematic. She's particularly sharp on the mechanics that trip up student writers most often: comma splices, subject-verb agreement in complex senten...

Comma splices, dangling modifiers, subject-verb agreement — Erika zeroes in on the specific grammar patterns a student keeps tripping over rather than rehashing rules they already know. Her experience editing college essays and teaching SAT Writing gives her a sharp eye for the errors that cost poin...

Scoring a 1550 SAT and 36 ACT required Rhea to master the grammar rules that standardized tests love to exploit — comma splices, subject-verb agreement across long modifiers, and parallel structure in complex sentences. She breaks these patterns down into clear, repeatable rules so students can spot...

Clear technical writing demands precise grammar, and Jeffrey has spent years refining that skill through research papers, grant applications, and academic publications in his engineering PhD program. He digs into the mechanics that trip students up most — subject-verb agreement in complex sentences,...

Trained as a journalist at Columbia, Sharon treats grammar not as a set of arbitrary rules but as the mechanics behind clear communication. She digs into the logic of sentence structure — why a misplaced modifier changes meaning, how parallel construction strengthens a list, when a semicolon actuall...

Sentence structure follows rules as logical as any equation, and Earnest teaches grammar with that same clarity — breaking down when to use semicolons versus em dashes, how subordinate clauses function, and why parallel structure makes writing stronger. His 1530 SAT score reflects sharp command of w...

Years of legal writing — where a misplaced modifier can change the meaning of a contract — gave Tiffany an unusually precise command of grammar. She unpacks rules around subject-verb agreement, comma usage, and parallel structure by showing students how each choice affects clarity, turning grammar f...

Between ACT prep, college essays, and biochemistry lab reports, Zachary has edited enough student writing to know exactly where grammar falls apart — usually in the same handful of places. He zeroes in on those recurring trouble spots, like misused semicolons or pronoun case errors, and teaches the ...
