Do I need to create an account to track my progress?

Which exams does TypoGrammar prepare me for?

How is TypoGrammar different from Grammarly or Duolingo?

Grammarly fixes your sentences but rarely teaches the underlying rule. Duolingo gamifies short drills. TypoGrammar focuses on understanding - every lesson explains why a structure works, with examples, mistakes to avoid, and a quick quiz to lock it in.

How long does it take to see results with TypoGrammar?

Most learners report a noticeable improvement in writing accuracy within 2-3 weeks of daily 15-minute sessions. The verb-tenses quiz gives you a personal weak-area breakdown, so you can target exactly the tenses you keep getting wrong.

Can I use TypoGrammar on my phone?

Yes - the entire site is mobile-first. Lessons, quizzes, and the grammar checker all work in any modern mobile browser. There is no app to install.

What is the difference between passed and past?

'Passed' is only ever a verb — the past tense of 'pass' (He passed the exam. Time has passed). 'Past' is never a verb; it works as an adjective (past events), noun (in the past), preposition (walk past the shop), or adverb (the car drove past).

How do I know whether to use passed or past?

Test: can you replace the word with another verb form like 'went by' or 'moved'? If yes, use 'passed' (a verb). If the word is modifying a noun or following a preposition, use 'past'. Example: 'We passed the museum' = we went past it (verb). 'The museum is past the bridge' = beyond the bridge (preposition).

Passed vs. Past: What's the Difference?

Quick Answer

passed = verb only — past tense of "pass" (He passed the test.)

past = adjective, noun, preposition, or adverb — never a verb

Explanation

PASSED (verb)

Past tense / past participle of "pass"

pass → passed → passed

"She passed her driving test."

"Time passed slowly."

"He passed the ball."

PAST (not a verb)

Adjective: "past events", "past mistakes"

Noun: "in the past", "forget the past"

Preposition: "walk past the shop"

Adverb: "a car drove past"

"In the past, things were different." (noun)

"Walk past the church." (preposition)

Quick test: Can you replace the word with "went by" or another verb? → use passed. Is it followed by a noun or acting as a noun/adjective? → use past.

Examples

✔Three months have passed since we met. (verb)

✔We need to learn from our past mistakes. (adjective)

✔The bus stop is just past the traffic lights. (preposition)

✔A stranger passed us on the road. (verb)
