Top Mistakes OxfordAQA IGCSE English as a Second Language Students Make (and How to Avoid Them)

Let's talk about the mistakes almost everyone makes

If you've sat a practice paper for this qualification and walked away wondering where all your marks went, you're honestly in very good company. Most of the oxfordaqa igcse english as a second language common mistakes students make aren't about not knowing English well enough. They're about small, fixable habits that quietly cost marks paper after paper. Let's go through the big ones, one at a time, and what to do instead.

Mistake one: misreading the command word

What goes wrong: A question asks you to "describe" something, and you launch straight into "explain why", or a question asks for your opinion and you write a neutral summary instead. It happens because we all read fast under exam pressure and our brain fills in what it expects to see rather than what's actually there.

Why it costs marks: Examiners mark against what the question actually asked. A beautifully written answer to a slightly different question than the one on the page simply can't earn full credit, no matter how fluent the English is.

What to do instead: Circle or underline the command word before you start writing. Give describe, explain, and give your opinion on their own two seconds of attention each time you meet them, because they genuinely ask for different things.

Mistake two: grammar slips that change the meaning

What goes wrong: Mixing up tenses when describing something that happened, is happening, or will happen is one of the most common oxfordaqa igcse english as a second language errors in both writing and speaking. "I go to the cinema yesterday" isn't just a small slip; it can genuinely confuse a reader about when the event took place.

Why it costs marks: Tense errors don't just lose accuracy marks, they can obscure your actual meaning, which affects how well the examiner can follow and credit your ideas.

What to do instead: Before you submit any written answer, do one quick pass just for tense. Ask yourself, for every verb: is this describing the past, the present or the future, and does the verb form actually match?

Mistake three: incomplete explanations

What goes wrong: You state an opinion or a fact but never actually back it up. "I think tourism is good for my town" and then nothing. No reason, no example, no development.

Why it costs marks: Longer writing and speaking tasks are marked partly on how well you develop and support your ideas, not just on whether you state them. An unsupported opinion reads as thin, even when the grammar is flawless.

What to do instead: Get into the habit of following every opinion with "because" and at least one specific example. It's a small habit, but it transforms a bare statement into a properly developed point.

Mistake four: timing failures

What goes wrong: Spending too long polishing an early answer and then rushing, or completely running out of time for, a later one. This is one of the most avoidable oxfordaqa igcse english as a second language mistakes because it has nothing to do with your actual English ability.

Why it costs marks: A rushed or unfinished later answer, even on a task you understood perfectly well, scores far lower than a slightly less polished but complete one. An unfinished answer physically cannot earn marks for the parts that were never written.

What to do instead: Practise with a visible clock every single time, not just occasionally. Decide roughly how many minutes each task deserves before you start the paper, based on the marks available, and check in with yourself at the halfway point.

Mistake five: preparing memorised answers instead of flexible ones

What goes wrong: Learning a fixed paragraph or spoken answer by heart and reproducing it regardless of what the actual question asks. It feels safe in the moment, but it rarely quite fits.

Why it costs marks: Examiners can tell when an answer doesn't actually respond to the question in front of them. A memorised script that doesn't match the prompt loses marks for relevance, even if every sentence in it is grammatically perfect.

What to do instead: Practise with vocabulary and structures you can adapt, rather than whole answers you can only repeat. Learn the building blocks, not the finished house.

Mistake six: topic-specific misconceptions

What goes wrong: Treating the three themes, identity and culture, social and global issues, and study and employment, as separate boxes rather than areas that regularly overlap in a single task. Students prepare vocabulary for one theme and are thrown when a question blends it with another.

Why it costs marks: A response that only addresses one strand of a blended prompt misses part of what was actually asked, even if what is written is accurate.

What to do instead: When you revise, deliberately practise linking themes together, describing a hobby that involves travel, or a study choice connected to a social issue you care about, so blended prompts don't catch you off guard.

Mistake seven: treating listening and speaking as an afterthought

What goes wrong: Because reading and writing feel more familiar, easier to revise from a textbook, and easier to self-mark, students often let listening and speaking practice slide to whatever time is left over, rather than scheduling it deliberately.

Why it costs marks: Listening and speaking are assessed with the same seriousness as the written papers, and the skills involved, catching spoken detail on the fly, responding to a genuine, unscripted question, don't improve just by reading more. They need their own dedicated, active practice.

What to do instead: Block out specific time each week for listening to real spoken English and for speaking practice with a partner or teacher, protected the same way you'd protect time for a written past paper. Treat all four skills as equally deserving of a place in your schedule.

Mistake eight: ignoring the mark allocation

What goes wrong: Writing a single short sentence for a question worth several marks, or spending disproportionate effort perfecting a one-mark answer while a much bigger question further down the paper gets rushed.

Why it costs marks: Mark allocation is a direct signal from the exam board about how much development a question needs. Ignoring it means either leaving marks unclaimed on a bigger question or wasting time that a smaller question never needed.

What to do instead: Before answering, glance at how many marks a question is worth and let that number set your expectations for how much you need to write or say. A two-mark question rarely needs more than two clear points; a longer, more heavily weighted task needs real development.

Here's the honest truth: almost none of these mistakes are about your English not being good enough. They're about exam habits, and habits can be changed with a bit of deliberate practice.

A quick self-check before your next practice paper

• Did I read the command word carefully, or did I answer the question I expected rather than the one asked?
• Did I check my tenses in every written answer?
• Did I back up every opinion with a reason and an example?
• Did I time myself and check in at the halfway point?
• Am I practising flexible language, or memorised paragraphs?
• Have I given listening and speaking as much dedicated practice time as reading and writing this week?

Turning this into exam tips you'll actually remember

These oxfordaqa igcse english as a second language exam tips only work if you actually apply them in practice, not just read them once and nod along. Pick one mistake from this list, focus on fixing just that one in your next practice session, and move on to the next once it's genuinely under control. Trying to fix all seven mistakes at once usually means fixing none of them properly.

Most students who struggle with this exam aren't missing knowledge, they're missing these small habits. Fix the habits, and the marks tend to follow. Give yourself credit for every mistake you catch in practice rather than in the real exam room. That's exactly what practice is for.

And if you only remember one thing from this whole list, make it this: examiners aren't looking for reasons to take marks away. They're working through a mark scheme trying to find every point you've legitimately earned. Read carefully, answer exactly what's asked, back up your ideas, watch the clock, and give every skill, including listening and speaking, its own fair share of your practice time. Do that consistently, and most of these mistakes simply stop happening.
