Complete the dramatic diary entry of a high-school student trying to survive finals week. Drag the correct words to complete the sentences.
My biology textbook is heavier than a small car. The final exams are approaching faster than a cheetah on roller skates. Thankfully, I am fueled entirely by coffee and sheer panic.
My biology textbook is heavier than a small car.
"Textbook" is a third-person singular subject (it), so it takes the verb "is".
The final exams are approaching faster than a cheetah on roller skates.
"Exams" is a plural subject (they), which requires the plural verb "are".
Thankfully, I am fueled entirely by coffee and sheer panic.
The first-person singular pronoun "I" always takes the verb "am".
Be
The verb be is the most irregular and most-used verb in English. It has eight forms — be, am, is, are, being, was, were, been — more than any other English verb. It works as both a main verb (linking a subject to a complement: She is a doctor) and an auxiliary (forming the progressive tenses I am working and the passive voice It was written).
Almost every sentence you'll ever speak or write uses some form of be. Master its irregular forms early — am/is/are/was/were/been — and the rest of English grammar gets dramatically easier.
Present tense
The present tense in English has four forms: simple present (I work) for habits, general truths, and stative descriptions; present progressive (I am working) for actions happening right now or temporary situations; present perfect (I have worked) for past actions with present relevance; and present perfect progressive (I have been working) for ongoing actions continuing into the present.
The simple/progressive distinction is one of the trickiest jumps for learners — I work in Paris (habitual) and I'm working in Paris (temporary, right now) feel almost identical but signal different things. Pick wrong and your meaning subtly shifts.
Humor
The Humor tag marks questions and challenges where the author has tried — subjectively, deliberately — to make the practice itself entertaining. Expect characters, scenarios, and storylines that play with absurdity: zombies, alien tourists, a chef's disaster, a roommate's complaint. The grammar rule is real; the wrapping isn't.
Humor matters because grammar drills are forgettable. Tying a rule to a story your brain wants to keep makes it stick. Filter by Humor when motivation is what you're short on, not study time.
A2 | Elementary | Pre-intermediate
A2 is the elementary level in the CEFR framework, sitting between A1 and B1. At A2 you can handle routine exchanges — ordering food, asking directions, making small talk — and describe your immediate environment in simple sentences.
Grammatically, A2 introduces past simple and past continuous, present perfect for experiences, basic modal verbs, and the first conditional. You're also picking up collocations and learning which verbs take gerunds vs. infinitives. Knowing your level here is the difference between confident progress and frustration: A2 material consolidates the basics; B1 will overwhelm you.
Difficulty: Easy
The Easy difficulty tag marks questions and challenges aimed at beginners — typically A1 or early A2 level. Expect single-rule focus, short sentences, common everyday vocabulary, and one clear correct answer. Distractors usually rule themselves out quickly.
Filter by Easy when you're rebuilding fundamentals, warming up before harder material, or testing whether you've truly internalised a basic rule before moving on. Easy doesn't mean trivial — it means the rule itself is unambiguous and the context doesn't pile on extra complications.
