Feelings & Reactions: Bored vs Boring
Participle Adjectives: -ed vs. -ing
Are you bored or is the movie boring? In English, participle adjectives ending in -ed describe how someone feels, while those ending in -ing describe the thing or person that causes the feeling. For example, a terrifying horror movie makes you feel terrified.
This challenge covers how to correctly use these adjective pairs in everyday contexts. You will navigate tricky situations like complaining about an exhausting science lecture, surviving a boring museum date, and reviewing a fascinating documentary about competitive ironing. You'll also practice pairing these adjectives with the correct prepositions, such as being "bored with" a repetitive summer job.
You'll work through 10 questions featuring drop-down, single-choice, multi-choice, and drag-and-drop formats.

Adjective
If you've ever written a French nice old wooden table and felt something was wrong without knowing why, you've hit the adjective-order rule. English insists on a particular sequence (opinion, size, age, shape, color, origin, material) and rearranging the words makes a sentence sound non-native even when every individual choice is correct.
An adjective describes a noun or pronoun: a tall building, the soup is hot. Most adjectives also take comparative and superlative forms (taller, tallest), which is how you compare things, another core piece you need from day one.
Comparative and superlative
If you've ever doubled up (more better, the most cleverest), you've felt the most common comparative mistake. The fix is small but immediate: every adjective gets one comparative pattern, never both. Once you internalise which words use -er/-est and which use more/most, comparing things stops being a guess.
The comparative form compares two things (taller, more polite); the superlative picks the extreme of three or more (the tallest, the most polite). Short adjectives typically take -er/-est; longer ones use more/most. A small set are irregular: good → better → best, bad → worse → worst.
Infinitive
If you've ever written I enjoy to swim or He let me to go and only later learned why both are wrong, you've hit the infinitive's main puzzle. English is fussy: some verbs demand the to-infinitive, some demand the bare infinitive, some demand the gerund, and a few accept multiple options with different meanings (remember to lock vs remember locking).
The infinitive is the basic form of a verb, used non-finitely. The to-infinitive (to go) follows verbs like want, decide, plan; the bare infinitive (go) follows modal verbs (can, will) and causatives (Let him go).
Participle
If you've ever written I should have went and been corrected to should have gone, you've hit the past participle's main rule. The participle isn't an exotic form; it's the workhorse that builds perfect tenses, passive voice, and dozens of common adjectives. Get the irregular ones automatic and your tenses fall into place.
A participle is a verb form acting as an adjective or adverb. The present participle is the -ing form (running, sitting); the past participle is -ed (regular: walked) or irregular (broken, gone, written). Participles build perfect tenses, progressive tenses, and the passive.
Preposition
If you've ever written I'm interested on you (should be in) or I'm good on football (should be at), you've hit prepositions' main pitfall. Their choice is mostly idiomatic, not logical, and rarely matches what your native language does. Memorizing the right preposition for each common verb and adjective is what stops your speech from sounding subtly off.
A preposition is a small word linking a noun or noun phrase to other parts of the sentence: in, on, at, to, from, with. Marks time, place, manner, or abstract relationships. Choice is largely idiomatic, especially in fixed combinations (depend on, good at, afraid of).
Collocations
If your English vocabulary is large but your speech still sounds slightly off (do a mistake, powerful coffee, high winds blew strongly), you've hit the collocation problem. Each word is correct in isolation, but native speakers don't pair them that way. Fixing it isn't about more vocabulary; it's about learning words in their natural company.
Collocations are word combinations that habitually occur together: make a decision, strong coffee, heavy rain, highly unlikely. The grammar permits other pairings, but fluent English consistently chooses one over the rest. They're the connective tissue of natural-sounding language.
B1 | Intermediate
If you can hold a conversation about your weekend, explain why you're late, and follow a short news story without panicking (but still feel lost in fast or technical English) you're probably operating at B1. Knowing this matters: study material at the wrong level either bores you or burns you out, and B1 is the typical target for travel, casual work, and most everyday social English.
B1 is the intermediate level in the CEFR framework, where you handle everyday English independently and start combining ideas with complex sentences, passive voice, and modal verbs.
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.
