Thirty days out from AEIS, most overseas families panic and do exactly the wrong thing: buy three more assessment books, double daily hours, and start a brand new tutor. I've watched this fail enough times to write it down. The AEIS final 30-day sprint is not about adding — it is about subtracting noise, calibrating timing, and protecting the one thing that wins on test day, which is a child who can still think clearly under pressure.
What the AEIS final 30-day sprint is actually for
The last month is consolidation, not acquisition. By now your child either knows fractions, ratios, and how to write a 150-word composition, or they don't. Trying to teach a new Math topic 18 days before the test usually backfires — it crowds out review of the 80% they already half-know, and that 80% is where the marks live.
A useful mental model: in 30 days you can lift a child from a 55% mock score to maybe 68%. You cannot lift them from 30% to 65%. If you are in the second category, read the AEIS complete guide for 2026 again and consider whether September S-AEIS is the more honest target.
So what does this sprint do?
- Tightens timing on each section so no one runs out of time
- Converts "I sort of know this" into "I get this right under pressure"
- Builds an error log the child actually uses
- Protects sleep, eyes, and morale through AEIS exam week
That's it. Four jobs.
Week 1 (Day 30 to Day 23): diagnose, don't drill
The biggest mistake I see in AEIS last month prep is jumping straight into mock paper after mock paper. Before any of that, spend the first 3 days doing one cold mock per subject under exam conditions, then sitting with your child to categorise every single wrong answer into one of four buckets:
| Error type | What it means | Fix |
|---|---|---|
| Concept gap | Doesn't understand the topic | Targeted re-teach, 1-2 sessions |
| Careless | Knew it, misread or miscalculated | Process change, not more practice |
| Timing | Couldn't reach the question | Section pacing drills |
| Language | Couldn't decode the question wording | Math word-problem vocabulary |
Most overseas children — especially those from China, Vietnam, or Indonesia — score lower on Math than their domestic ability suggests, purely because of the language wrapper. They can solve "甲比乙多3", but freeze on "John has 3 more marbles than Peter, who has half as many as…". This is a language fix, not a math fix.
After diagnosis, build a one-page weakness map. Five items max. If everything is a weakness, your priorities are wrong.
Days 25-23: re-teach the top 2 concept gaps only. For Math, this often means revisiting the bar model approach — see the AEIS math model drawing method for why this single technique unlocks roughly 30-40% of the Primary-level word problems.
Week 2 (Day 22 to Day 15): timed sections and the error log
Now you start the structured part of the AEIS final 4 weeks plan. The unit of practice shifts from "whole papers" to "timed sections."
A typical weekday in week 2:
- 60 min: one timed English section (vocabulary + grammar OR comprehension)
- 60 min: one timed Math section (15 questions in 30 min)
- 30 min: error log review from yesterday
- 30 min: vocabulary (50 words/day, spaced repetition)
Total: ~3 hours of focused work, plus light reading at night.
The error log is non-negotiable. A simple notebook works fine — left page is the question (cut and paste or rewritten), right page is what went wrong and the corrected solution in the child's own handwriting. If your child can't explain their error in their own words, they haven't actually fixed it. They've just seen the answer.
By Day 15, the error log should have 80-150 entries. The child should be able to flip through it and say "oh yeah, I always mix up 'fewer' and 'less'" or "I forget to convert units in speed problems." That recognition — not the volume of practice — is what carries marks on test day.
Weekends in week 2: one full mock paper on Saturday, full review on Sunday. Not two mocks. Two mocks per weekend is how children learn to hate the test.
Week 3 (Day 14 to Day 8): full mocks and pacing
This is the hardest week. Two full mock papers under exam conditions, ideally at the same time of day as the actual AEIS slot. Print the answer sheets. Use a real timer. No phone. No snack breaks mid-paper. If the real test starts at 9am, your mock starts at 9am.
What you're calibrating in week 3:
-
Question order strategy. Does your child do questions in order, or skip the hard ones first? By now they should have a strategy and stick to it. AEIS Math has roughly 20% questions that eat 50% of the time if attempted in order — knowing when to skip and return is a learned skill.
-
Time per section. For English comprehension, aim for ~1.5 minutes per question average, leaving 5 minutes for review. For Math, ~2 minutes per question on average. Children who finish 10 minutes early usually have careless errors; children who run out of time usually skipped the skipping strategy.
-
The recovery move. Every test has one moment where the child hits a question they can't solve and panics. The recovery move — "circle it, move on, return in the last 10 minutes" — has to be muscle memory by Day 8.
A quick comparison of how week 3 mocks should look:
| Metric | Day 14 mock | Day 8 mock |
|---|---|---|
| Score | Baseline | +5 to +10 marks |
| Unfinished questions | 3-6 | 0-2 |
| Careless errors | 5-8 | 2-4 |
| Energy after paper | Exhausted | Tired but okay |
If your Day 8 mock looks worse than Day 14, the child is over-trained. Cut hours immediately.
Week 4 (Day 7 to Day 1): taper, don't cram
Athletes call this the taper. Volume drops, intensity stays moderate, sleep extends. The same applies to AEIS.
Day 7 to Day 4:
- One timed section per subject per day, no full mocks
- 45 min error log review daily
- Re-read the top 5 model compositions (don't write new ones)
- Bed by 10pm, no screens after 9pm
Day 3 to Day 2:
- Half the practice volume of Day 7
- Walk through the test venue route on a weekday at the same time of day
- Confirm documents — admission slip, passport, ID, stationery, water bottle. The AEIS registration document checklist covers what must be in the bag
Day 1 (the day before):
- Morning: 60 min light review of error log, one 20-min reading passage
- Afternoon: free. Outdoor walk, light meal, no Math
- Evening: pack the bag, lay out clothes, in bed by 9:30pm
I've had parents email me on Day 1 asking whether their child should "just do one more paper." The answer is always no. One more paper on Day 1 buys nothing and risks a low-confidence finish that the child carries into the exam hall.
AEIS exam week: the actual logistics
AEIS exam week is when families who prepared well still lose 5-10 marks to logistics. Don't be that family.
Sleep. Two nights before the test matters more than the night before — adrenaline often disrupts D-1 sleep, so banking rest on D-2 is the real lever.
Food. Whatever your child normally eats. Now is not the time for a "brain breakfast" of foods they've never tried. A normal bowl of porridge or eggs and toast beats a green smoothie they're suspicious of.
Travel buffer. Arrive 45 minutes early. Singapore traffic on a school morning near test centres is unpredictable, and a stressed arrival costs marks for the first 20 minutes of the paper. If you're not based in Singapore yet, the moving to Singapore with school-age kids checklist walks through where to stay during the test window.
During the paper. Tell your child: if they finish 15 minutes early, they check the work. They do not leave early. Every year a small number of children walk out 20 minutes early and lose marks they would have caught on review.
Between Day 1 and Day 2 of testing. No post-mortem. Do not ask "how did it go?" Do not let the child re-check answers online. The only thing that matters is showing up rested for the second paper. If they did badly on Day 1, they need confidence on Day 2, not confirmation of failure.
What to cut from your AEIS final 30-day sprint
Things parents add in the last month that hurt more than help:
- A new tutor starting in week 1 of 4 — the relationship-building tax alone costs a week. If you didn't have a tutor by Day 60, consider whether the AEIS tutor ROI math still works at this stage; often a tighter self-study plan beats a panic hire.
- New assessment books with unfamiliar question styles
- Switching to a different model paper publisher
- Adding a third subject (general ability) on top — for Primary AEIS this is a mistake; the existing two subjects already saturate prep capacity
- Weekend "intensive camps" of 8+ hours
Subtraction is the underrated skill of the final 30 days. The parents whose children pass are usually doing less in week 4 than they were in week 1 — but doing it better.
Frequently Asked Questions
Is 30 days enough to prepare for AEIS from scratch?
No. Thirty days is a sprint, not a foundation. It works if your child has already done 3-6 months of structured prep and needs to consolidate. If you are starting from zero in English or Math, a 30-day window will not close a two-year curriculum gap.
How many hours per day should we study in the final month?
Plan for 3-4 focused hours on weekdays and 5-6 hours on weekends, with one full rest day per week. More than that and accuracy drops, sleep suffers, and the child arrives at AEIS exam week burnt out. Quality of recall matters more than total hours logged.
Should we still take new mock papers in the last week?
Stop full new mocks 5-7 days before the test. In the final week, only redo papers your child has already done, focus on the error log, and run timed sections — not whole papers. The goal is calibration and confidence, not surprise.
What if my child's mock scores are still failing 30 days out?
Be honest about the gap. If English vocabulary is below around 2,500 words or Math is stuck on Primary 4 topics, AEIS is unlikely this cycle. Use the 30 days to lock in fundamentals for the September S-AEIS retake instead of cramming everything.
How do we handle the day before the AEIS exam?
No new content. One light review of the error log, one timed 20-minute reading passage to keep the brain warm, then stop by 3pm. Pack documents, print the admission slip, eat normally, sleep by 9:30pm. Anxiety on D-1 is normal — activity beats rumination.
What to do now
- Run one cold mock per subject this week and build the four-bucket error map before doing anything else.
- Cut your current study plan by 20% if your child is doing more than 4 hours weekdays — over-training in week 1 destroys week 4.
- Lock the error log into a single notebook today; if it's spread across three apps, it's not an error log.
- Calendar the taper: Day 7 onwards is reduced volume, not "one final push."
