When you finally hit “export to PDF” on your IA, it can feel like closing a chapter. The funny part is that most marks aren’t lost in the big dramatic places (the idea, the ambition, the hours). They slip away in quieter ways: a research question that’s slightly too wide, a method that can’t be replicated, analysis that never quite says “so what,” or formatting that makes a marker work harder than they should.
The good news is that the most common IA mistakes are predictable. And if they’re predictable, they’re avoidable.
If you want a fast look at what strong work actually looks like, start by browsing RevisionDojo’s coursework exemplars. A good exemplar doesn’t just inspire you. It calibrates your sense of what “enough” looks like for an IA.
IA Mistakes: a quick checklist to self-audit
Use this as a five-minute reset before you write (and again before you submit):
-
Is my IA research question focused enough to answer with depth?
-
Does every section clearly earn marks from the rubric?
-
Do I analyse and evaluate, not just describe what happened?
-
Am I using my word count for reasoning, not background?
-
Are my sources and data reliable, traceable, and appropriate?
-
Is the final draft clean: citations, labels, units, and formatting consistent?
For more subject-specific structure and criteria reminders, the fastest reference is RevisionDojo’s IA Guides.
Mistake: choosing an IA topic that’s too broad
A broad topic feels safe because you’ll “have lots to say.” But in an IA, breadth usually turns into rushed writing. Markers reward depth: precise choices, clear boundaries, and a sense that you controlled the investigation instead of letting it sprawl.
A simple test: if your IA question could be answered by reading three textbooks, it’s probably too wide. If it can be answered with a manageable dataset, a specific case study, or a tight comparison, you’re in the right zone.
Try this narrowing move:
-
Start with your big interest.
-
Choose one context (time period, location, sample, text, dataset).
-
Choose one measurable relationship (variable A affects variable B).
-
Add a constraint (age group, range, conditions, or timeframe).
If you’re stuck, follow a proven path: read one strong model in the same subject from RevisionDojo’s coursework exemplars, then compare how narrow their scope is compared to yours.

Mistake: ignoring the rubric until the end
Many students treat the rubric like a formality. Markers do not. Your IA is not graded on effort, originality, or how “smart” it sounds. It’s graded on evidence that matches criterion descriptors.
A practical habit: do a “rubric-first outline.” Before you draft paragraphs, draft the marks. Write one bullet per criterion explaining what evidence you will show.
Two useful reads when you want to think like a marker:
If you want a concrete example of how criteria are unpacked, see Language A Internal Assessment (IA) Rubric (even if you don’t take Language A, the principle is the same: descriptors want visible proof).
Mistake: staying descriptive instead of analytical
Description feels productive because you’re writing sentences and adding information. Analysis feels slower because it forces choices: what matters, why it matters, and what it implies.
A quick upgrade rule for almost any IA paragraph:
-
Description tells what happened.
-
Analysis explains why it happened.
-
Evaluation asks how reliable the claim is and what could change it.
After every key result, ask:
-
“So what does this mean for my research question?”
-
“What alternative explanation could exist?”
-
“How confident am I, and why?”
This is where RevisionDojo can speed up your loop. Use Jojo AI Chat to challenge one paragraph at a time: “What would stronger evaluation look like here?” Then convert the recurring fixes into habits using RevisionDojo Flashcards.
Mistake: wasting word count on the wrong sections
Your word count is a budget. Most students overspend on introductions and background because it feels like “setting the scene.” Markers rarely award many marks for scene-setting. They award marks for method quality, reasoning, interpretation, and reflection.
A healthier allocation mindset:
-
Background should exist only to make your investigation understandable.
-
Your results should be clear and labelled.
-
Your analysis and evaluation should do the heavy lifting.
If you’re unsure how tight good writing looks within limits, scan a few high scoring samples in RevisionDojo’s coursework exemplars and pay attention to what they don’t include.
Mistake: using weak sources or shaky data
Your IA can be beautifully written and still collapse if the foundations are unreliable. Markers want traceable, credible, appropriately academic sources and data that is either well-collected or responsibly selected.
Basic rules that keep you safe:
-
Prefer peer-reviewed articles, academic books, reputable databases, and official reports.
-
If you use secondary data, justify why it’s appropriate and note limitations.
-
If you collect primary data, make the method replicable and control variables where possible.
In sciences, this often shows up as vague methodology or missing units. In humanities, it shows up as overreliance on general websites. In all subjects, it shows up as claims that don’t have support.
Mistake: skipping proofreading and “marker-friendly” formatting
Formatting sounds cosmetic until you realise it changes how your work is read. A marker who can’t quickly interpret your graphs, tables, citations, and headings will miss your best points or spend less time appreciating them.
Final-hour checklist:
-
Every figure and table is labelled, referenced, and readable.
-
Units are consistent.
-
Citations are complete and consistent.
-
Headings guide the reader through the IA logic.
If you want a structured way to catch issues earlier, use RevisionDojo’s grading tools to make feedback less emotional and more mechanical: identify what to fix, fix it, then re-check.
A simple IA recovery plan (that still protects exam prep)
One trap is letting the IA consume all revision time. Keep a feedback loop, but keep it contained.
A realistic weekly approach:
-
Two focused IA sessions (rubric-driven revisions only)
-
Three exam sessions using RevisionDojo’s Questionbank to keep skills sharp
-
Daily 10-minute recall using RevisionDojo Flashcards
If you want a broader system for balancing coursework with exams, How to Study for IB Exams: Step-by-Step Guide pairs well with a busy IA season.
Conclusion: make your IA easy to mark well
A strong IA isn’t the one with the fanciest idea. It’s the one that stays focused, follows the rubric closely, prioritises analysis, respects the word count, uses credible sources, and lands cleanly with careful proofreading.
If you want the fastest way to level up, do two things this week: (1) compare your draft to one high-scoring model in RevisionDojo’s coursework exemplars, and (2) run a rubric-first revision cycle using RevisionDojo’s tools. Then protect your exam prep with daily Flashcards and targeted Questionbank practice, so your IA improves without quietly stealing your final months.
