Sorry I missed the meeting! I ___ completely convinced it was on Thursday.
The correct answer is was.
For the first-person singular pronoun "I", the correct past tense form of the verb "to be" is always "was".
Be
Be vs have vs do: all three serve as auxiliaries, but be builds progressives (is running) and passives (was broken); have builds perfects (has gone); do builds negatives and questions (do you, doesn't, did). Only be also works as a main verb (copula: She is a doctor).
The verb be = 8 forms, most irregular English verb. Copula (links subject to complement) + auxiliary for progressive/passive.
Diagnostic: is be followed by an -ing form? → progressive auxiliary. Past participle? → passive auxiliary. Adjective/noun/prepositional phrase? → copula (main verb).
Past tense
Simple past vs past perfect: simple past puts events on the main timeline (I arrived. She left.). Past perfect marks an event as earlier than another past event (She had left before I arrived). If all events are in sequence, simple past is enough. Only use past perfect when you need to show "earlier than the main story."
The past tense has four forms encoding different temporal relationships: simple past, past progressive, past perfect, past perfect progressive.
Diagnostic: are events in sequence? → simple past is fine. Need to show one event happened before another past event? → past perfect for the earlier one.
A2 | Elementary | Pre-intermediate
A2 vs B1: A2 handles routine transactions and simple past narration. B1 handles connected discourse, explaining reasons, and understanding main points in clear standard speech. If you can tell what happened but not why it matters, you're still A2.
A2 is the elementary level of the CEFR: past simple, present perfect, first conditional, basic modals, and routine communication about familiar topics.
Diagnostic: can you link ideas with because, although, so that and hold a conversation beyond scripted topics? No → A2. Yes → moving into B1.
Easy
Easy vs Medium vs Hard: Easy = one rule, obvious answer, A1–A2. Medium = one rule but realistic distractors, A2–B1. Hard = interacting rules, edge cases, B2+. Start Easy to check you have the basics before moving up.
The Easy tag filters for single-rule, short-sentence, common-vocabulary challenges designed for beginners or for anyone wanting a confidence check on fundamentals.
Diagnostic: if you get Easy questions wrong, stay here — your foundations need work. If they feel trivial, move to Medium.
