Tenses in English Grammar (IELTS): What Actually Costs You Marks

If you already “know” the twelve tenses but still lose marks on Grammatical Range and Accuracy, the problem usually isn’t that you don’t understand tenses in English grammar — it’s that a handful of specific confusions keep resurfacing under exam pressure. This guide covers all twelve forms, but it spends the most time on the three or four mix-ups that examiners flag repeatedly: the present perfect vs. the past simple, the past-continuous-plus-past-perfect combination, and dropped auxiliaries in the future perfect. Get comfortable with those, and the rest falls into place fast.

Quick Reference: All Twelve Tenses in English Grammar

Keep this table open while you read — it’s the fastest way to see how these tenses in English grammar fit together before the sections below explain the why behind each row, not just the formula.

The Confusion That Costs the Most Marks: Present Perfect vs. Past Simple

This is the single most common source of tense errors among IELTS candidates, and it’s worth isolating on its own rather than burying it inside a general “present tenses” section.

• Past simple names a finished action tied to a specific, stated or implied time: “I visited Paris in 2019.” The time is closed — it happened, it’s over, and you’re reporting it as history.
• Present perfect connects a past action to the present moment, usually without stating exactly when: “I have visited Paris.” The emphasis is on the fact that the experience exists now, not on when it happened.

The test that actually works in practice: if you can attach a specific past time marker (“yesterday,” “in 2019,” “last month”), you need the past simple. If the sentence is about accumulated experience, an unfinished time period (“this year,” “so far”), or a result still relevant now (“I have lost my keys” — I still don’t have them), you need the present perfect.

This distinction shows up constantly in Writing Task 1: “The graph shows that unemployment has risen since 2015” (an ongoing trend, present perfect) versus “Unemployment rose sharply in 2016” (a specific, closed data point, past simple). Mixing these up doesn’t just cost a grammar point — it can misrepresent what the data actually shows.

Present Tenses in Practice

Beyond the perfect/simple distinction above, the present tenses in English grammar hold one more common trap: candidates often use the continuous for permanent facts by mistake (“water is boiling at 100°C” — wrong; it’s always true, so it needs the present simple: “water boils at 100°C”). Reserve the continuous for genuinely temporary or in-progress situations, and reserve the simple for anything permanent, habitual, or universally true.

• Fact (simple): Water boils at one hundred degrees Celsius.
• Trend (continuous): More people are using digital libraries these days.
• Experience (perfect): I have finished my research on literary history.
• Duration (perfect continuous): She has been teaching English for ten years.

Past Tenses: Getting the Sequence Right

The past tenses in English grammar are usually straightforward on their own — most learners can produce “I visited,” “I was visiting,” or “I had visited” without much trouble in isolation. The difficulty appears when two past events need to be placed in relation to each other, which is exactly what Speaking Part 2 stories and narrative-style Task 2 examples demand.

The rule that resolves almost every case: use the past perfect for whichever event happened first, and the past simple for whichever happened second (or is the “main” event of the sentence).

“The train had left when I reached the station.” — leaving happened first (past perfect), arriving happened second (past simple). “It was raining when the match started.” — the rain was already in progress (past continuous) when the match began (past simple).

If you’re ever unsure which past tense to use, ask: is this the background, the interruption, or the event that came before everything else? That question alone resolves most of the confusion.

Future Tenses: Prediction vs. Plan vs. Completion

IELTS Task 2 essays constantly ask you to predict outcomes, and future tenses in English grammar actually distinguish between several kinds of statement — which is worth knowing explicitly rather than defaulting to “will” for everything.

• Will — a prediction or belief, not a fixed plan: “Automation will likely replace many routine jobs.”
• Going to — a plan or intention already decided (not in the table above, but worth knowing): “The government is going to introduce new regulations.”
• Future perfect — a specific completion point: “By 2030, many countries will have adopted stricter emissions targets.”

Using “will” for everything isn’t wrong, exactly, but it flattens your argument — a strong Task 2 essay uses the future perfect specifically when you want to name a deadline or milestone, because it signals precision the plain future simple doesn’t.

• Prediction: Artificial intelligence will improve the accuracy of translations.
• Deadline (perfect): We will have finished the syllabus by December.
• Duration (perfect continuous): By then, she will have been working there for twenty years.

The Errors Examiners See Most Often

These four patterns account for the large majority of errors with tenses in English grammar:

1. Missing third-person -s: “the researcher analyze” instead of “analyzes.” A single letter, but examiners read it as a control issue, not a typo — it happens too consistently across essays to be dismissed as one-off.
2. Dropped auxiliaries in perfect and future-perfect forms: “they will finished” instead of “they will have finished.” Under time pressure, the auxiliary is the first thing writers cut — train yourself to check for it specifically.
3. Tense drift within a paragraph: starting a narrative in the past simple and sliding into the present halfway through, with no reason for the shift. Pick your anchor tense for a passage and stay with it unless the meaning genuinely changes.
4. Present perfect used with a specific past time marker: “I have visited Paris in 2019” — the “in 2019” forces past simple (“I visited Paris in 2019”). This is the single clearest signal examiners use to check whether a candidate actually understands the present perfect or is using it decoratively.

A 60-Second Self-Editing Checklist

Before you submit any piece of writing, run through this in order — it takes less time than it looks:

1. Scan every perfect-tense verb (have/has/had/will have + past participle) and check the auxiliary is actually there.
2. Check every present-perfect sentence for a specific time marker (“in 2020,” “yesterday,” “last month”). If one is present, switch to past simple.
3. Trace two-event sentences: whichever event happened first should be in the past perfect, not the past simple.
4. Read your paragraph’s verbs in isolation, ignoring the rest of the sentence — do they stay on one timeline, or does the tense drift without reason?
5. Check third-person -s on every present-simple verb with a singular subject.

The Takeaway

Tenses in English grammar aren’t twelve rules to memorize in isolation — they’re four aspects (simple, continuous, perfect, perfect continuous) applied to three time periods, and almost every real error comes from a small number of predictable confusion points rather than a gap in general knowledge. Learn to catch present perfect used with a specific time marker, get comfortable sequencing two past events with the past perfect, and build the habit of checking for dropped auxiliaries — and your grammatical accuracy will improve faster than reviewing all twelve forms from scratch ever would.
