Which grammar mistakes do TOEFL students make most?

We read the corrections in the 8,000 most recent writing responses we evaluated, and 362,540 sentence-building answers from the last six months. The grammar that costs students marks is not the grammar most textbooks spend the most time on. Conditionals and the passive, which fill whole chapters, were among the strongest areas, at about 83 percent correct. Word order was among the weakest: sentences with time and place phrases went wrong one time in three, and a single adjective-order sentence was missed two times in three.

These are counts of corrections in feedback, so they show what appears most often, not what costs the most on its own. The Grammar That Actually Moves Your Band explains which errors raters weigh most heavily.

What was corrected in student writing	Responses with at least one
Prepositions	About 3 in 4
Helper verbs (be, do, have)	About 7 in 10
Articles (a, an, the)	About 2 in 3
Singular and plural nouns	About 1 in 2
Punctuation and capitals	About 1 in 4
Verb and word forms	About 1 in 4

1 in 3Complete the Words boxes missed in 12,000 Reading sections

Words cost marks in Reading too. We looked at 123,670 Complete the Words boxes from 12,000 Reading sections taken since September: students missed a third of them. Of the misses, about one in four started right and ended wrong, like explosion where the sentence needed explosive, about one in six were a letter or two away from the right spelling, and nearly one in three were left empty. Word forms, spelling and academic vocabulary each train one of those, with the same half-word box the exam uses. When the box feels easy, take it into the real task in Complete the Words practice.

Why this is built for the exam

Students who write to us about grammar often say the same thing in different words: they know the rule, and under time pressure it disappears. So every level does three things a grammar book cannot.

Misses come back
A question you miss comes back at the end of the level.
A review list
Your mistakes stay in a review list until you get them right.
Speed rounds
Once you clear a level, a speed round replays it against the clock, because knowing a rule and using it without stopping to think are different skills.

When you are ready to use it for real, take a timed writing practice test or drill the exam tasks in Practice Exercises.

Common questions

Does the TOEFL test grammar?

There is no separate grammar section on the TOEFL iBT. Grammar counts inside other tasks: the sentence-building items in Writing test it directly, and the email and academic discussion are rated partly on how well you control your language. In Speaking, grammar is part of how your interview answers are rated.

How do I find my grammar and vocabulary weak spots?

Take the Grammar and Vocabulary Check above. It asks 28 questions across 14 skills and ranks them, weakest first, with no sign-up. If you have taken tests with us and are signed in, the page also reads your recent results and shows which grammar skills they point to.

Why practice word forms and spelling for the TOEFL?

Because the Reading task Complete the Words marks every typed letter. In 12,000 of our Reading sections, a third of the boxes were missed, and most misses were one of three things: the right start with the wrong ending, a letter or two off the right spelling, or a box left empty. Each of those has its own skill here.

Which grammar mistakes cost the most in TOEFL Writing?

Errors that block meaning cost the most, such as broken sentences and wrong verb forms. Small slips matter when they repeat, because a pattern tells the rater your control is limited. In our data the most frequent corrections were prepositions, helper verbs, articles and singular or plural nouns.

Is this grammar practice free?

Yes, to start. The Grammar and Vocabulary Check, the whole Articles skill and level 1 of every other skill are free, with no sign-up. Every paid plan opens all 560 questions, the remaining rules, the tutor tips and the speed rounds, across all 14 skills. There is no separate grammar purchase.

How long does it take to improve my grammar?

It depends on how many patterns you are fixing, so start with one rather than reviewing all of grammar at once. Work on a single weak skill in short sets, then use it in your own writing and speaking until it stops needing thought. A level takes about two minutes.
