The correct answers are Some of the cookies are missing! and All of them have completely vanished!
When using a quantifier with a specific group or an object pronoun (like "them"), you need "of the" or "of".
- Some of the cookies and All of them are correct.
- "Most the cookies" is missing "of" (Most of the cookies).
- "No of the cookies" is incorrect because "no" doesn't take "of"; it should be None of the cookies.
Determiner
If you speak a language without articles or demonstratives — Mandarin, Russian, Polish, Japanese, Korean — determiners are likely the most stubborn topic in your English. The rules feel small but the wrong choice (I went to home instead of I went home) immediately marks you as non-native. Mastering determiners is the highest-leverage move you can make for sounding natural.
A determiner comes before a noun to clarify which one, how many, or whose. Categories include articles (a/the), demonstratives (this/that), possessives (my/your), and quantifiers (some/many).
Pronoun
If you've ever paused before who vs whom, its vs it's, or me vs I — you've felt how much weight pronouns carry in English. They're tiny words but they're case-sensitive (I vs me), context-dependent, and one of the few places where everyday English still trips careful speakers. Get the common patterns right and you instantly sound more careful.
A pronoun is a closed class of small words that replace nouns or noun phrases. Types: personal (I, you, he…), demonstrative (this, that), relative (who, which), interrogative (who?, what?), reflexive (myself), and indefinite (everyone, nobody).
Quantifier
If you've ever written many information or much friends and been corrected, you've hit the quantifier-noun match. English splits its quantifiers based on whether the noun can be counted: many/few/several go with countable nouns, much/little go with uncountable. Use one with the wrong type and the sentence sounds clearly off.
A quantifier indicates vague quantity rather than a specific number: all, some, any, many, few, much, little, several, each, every, both. Splits into count quantifiers (with countable nouns) and mass quantifiers (with uncountables).
Negation
If your native language uses double negatives (I don't see nothing) — like Russian, Spanish, or French — you've probably been told this is wrong in English and not been entirely sure what the fix is. Standard English uses one negative per clause: either I saw nothing or I didn't see anything, never both. Once you internalise that single rule, your written English clears up a lot.
Negation in English uses not after an auxiliary or modal verb: I am not going. Without an auxiliary, you add do-support (I do not go). Negative words like never and nobody already negate the clause — adding not on top creates non-standard double negatives.
Countable and uncountable
If you've ever written informations, an advice, or furnitures — and only learned later that none of these exist in English — you've hit the countable/uncountable divide. The trap is that English's choice of which nouns count individually and which don't is partly arbitrary: information is uncountable; fact is countable; bread is uncountable; loaf is countable.
In English, nouns are either countable (chair, book) or uncountable (water, furniture, advice). Countable nouns take a/an, form plurals, and pair with many/few; uncountables don't pluralise and pair with much/little.
A2 | Elementary | Pre-intermediate
If you can order coffee, ask for directions, and tell someone what you did yesterday — but struggle the moment the conversation drifts into anything abstract — you're operating at A2. Knowing this matters: A2 is the level where most learners plateau because they reach for B2 material too early and burn out. Stay here and your foundations get unbreakable.
A2 is the elementary level in the CEFR framework, covering routine communication and the first wave of real grammar: past simple and continuous, present perfect, basic modal verbs, first conditional, and common verb-pattern rules.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
