Self-practice apps and PSLE tuition: which does your child need?
By Max Loo Pin Mok · 22 Jun 2026
Many parents ask me whether self-practice apps such as KooBits or the Ministry of Education's Student Learning Space (SLS) are enough to prepare a child for the PSLE, or whether a tutor is still needed. It is a fair question, and the best preparation should use both.
What self-practice apps do well
Apps like KooBits and SLS are useful, and I would never tell a parent to stop using them. SLS is free and built around the MOE syllabus; KooBits is motivating, with points and rewards that keep a child coming back. Both give a child a large number of questions to attempt and mark the answer instantly, which is exactly what a student needs for one thing above all: practice volume. As I have written before, most common PSLE Maths errors — transfer errors, calculation mistakes, unit conversion slips — are overcome simply by doing many questions. A self-practice app is an efficient way for students to keep trying.
Where self-practice apps reach their limit
The limit of any app is that it marks the answer, not the thinking. When a child gets a question wrong, an app can tell them that they are wrong, and often show the right answer — but it cannot sit beside them and explain why they keep making the same mistake, or notice that three different "careless" errors are really one misunderstood concept.
Apps are also strongest on questions with a single definite answer — multiple-choice and short numerical answers. The harder, multi-step problems that decide a PSLE grade need someone to read a child's working, not just their final number.
Where a tutor still matters
A good tutor does the thing an app cannot: diagnose. From a handful of attempts, an experienced tutor can see the recurring misconception behind a string of wrong answers and fix the cause, not just the symptom. A tutor explains a full worked solution in a way a child understands and adapts the explanation when the student still has difficulty understanding. This is what families pay tuition centres and private tutors for — and it works.
The catch is cost. One-to-one tuition in Singapore is expensive, and not every family that wants this guidance can afford a full private-tutor rate.
A third option in between
This is the gap our service is built to fill — deliberately positioned between a self-practice app and a private tutor.
On our Q&A forum e-Portal, a student can run through PSLE questions and get marked instantly, just like an app, for multiple-choice and definite-answer questions. But unlike a generic app, the questions are built around past PSLE papers. Most questions have a full worked solution — and the answer is revealed only after the student attempts it, so they practise by active recall rather than reading the answer first. And when a child is genuinely stuck, there is a real tutor who replies — every day, including weekends and public holidays.
In other words: the instant practice of an app, the worked PSLE solutions and human help of a tutor, at a fraction of a private tutor's price.

Advice for parents
My advice is not to choose between the two. Let your child use SLS or KooBits for daily drilling — the repetitions are valuable and the apps make them easy. But for the questions your child keeps getting wrong, and for the worked solutions and explanations an app cannot give, bring in a tutor. The combination — steady self-practice plus a human who can diagnose and explain — beats either one on its own, and it is how a child moves from "doing lots of questions" to actually understanding them in time for the PSLE.
