The correct answers are the, no article, and no article.
Geography has tricky article rules!
- We use the for mountain ranges (like the Alps or the Himalayas).
- We use no article for continents (Asia, Europe, Africa).
- We use no article for individual mountains (Mount Everest, Mount Kilimanjaro, Mont Blanc).
Article
A/an vs the vs no article: the three-way choice that trips up learners whose first language has no articles (Russian, Japanese, Korean, Mandarin). Each option changes meaning — I saw a dog (any dog) vs I saw the dog (the specific one) vs Dogs are loyal (the species).
Articles are determinatives that mark noun specificity. A/an = indefinite, first mention. The = definite, known referent. Zero article = generic or uncountable.
Diagnostic: ask does the listener already know which one? Yes → the. No, and it's countable singular → a/an. Generic or uncountable → zero article.
English Grammar Basics
Basics vs intermediate/advanced grammar: if you're unsure whether to study articles or conditionals, tense basics or reported speech — you need to check whether your foundations are solid first. Basics covers everything up to A2.
English Grammar Basics groups the core building blocks: nouns, verbs, adjectives, prepositions, present/past tenses, questions, and negation.
Diagnostic: if you still hesitate over she don't vs she doesn't, or a vs an — start here. Master these and intermediate topics stop feeling random.
Humor
Humor vs serious practice: both teach the same rules. The difference is engagement — funny material keeps you coming back and creates stronger memory hooks. If dry drills bore you into quitting, humorous practice is more effective because you actually do it.
The Humor tag filters for entertaining practice: silly contexts, wordplay, absurd examples — all testing real grammar rules underneath.
Diagnostic: if you find yourself dreading practice → try filtering by Humor. If you're preparing for a formal exam and want serious register → filter it out.
B2 | Upper Intermediate
B2 vs C1: B2 means effective communication on complex topics with some effort. C1 means effortless fluency with precise register control. If you can argue a point but still reach for words and make structural slips under pressure, you're B2.
B2 is the upper-intermediate CEFR level: mixed conditionals, complex passives, reported speech with backshift, participle clauses, and sustained written argument.
Diagnostic: does your writing read as "competent non-native" or "could be native"? The former → B2. The latter → C1.
Medium
Medium vs Easy: Easy has one obviously correct answer and clearly wrong distractors. Medium has one correct answer but plausible distractors — you need to actually know the rule, not just guess from sound.
The Medium tag filters for A2–B1 challenges with realistic difficulty: one rule per question, plausible alternatives, everyday contexts.
Diagnostic: if you're scoring 90%+ on Easy, move here. If you're below 60% on Medium, go back to Easy for that topic. Target 70–80% accuracy for maximum learning.
