How to read the reviews on this page
Three things worth knowing before you start.
- They come from Google Maps, not from our own form — Each one is public under our Google listing, together with the author's profile. Here we show reviews rated 4 and 5 stars; the full list, lower ratings included, is behind the link in the block below.
- We don't order or buy reviews — Not on review sites, not from influencers. We reply to Google reviews under our own name, but we don't edit or remove them.
- A review is someone else's experience, not yours — Their group, coach and child's age may be nothing like yours. That's why, next to the reviews, we give you things you can check yourself: the trial lesson, the terms and the questions to ask any school.
Six questions worth asking any school
Ours included. The answers say more than any number of stars on a review site.
- How many children are in a group, and what age?
With us, 5–10 children aged 8–18, split by level. A group of twenty is a lecture, not a class with practice alongside a coach.
- What do you not promise?
A school that cannot name the limits of its method usually does not know them. We say plainly: we do not promise marks, we do not diagnose, and we do not replace tutoring.
- Does the child work on their own material?
Techniques practised only on the course's examples stay inside the course. Here, part of every meeting goes to what the child has actually been set.
- Who runs the classes, and where are they from?
Worth asking for the coach's name rather than about “experienced staff”. The Space Memory method is the responsibility of Natalia Lubenets, co-founder of the school.
- What happens if we want to stop?
The question asked least often and the most practical one. The conditions should be readable before you pay, not after.
- Can we see a class before deciding?
With us that is what the free trial lesson is for. If a school shows nothing before payment, that is an answer in itself.
This list works both ways: if our answers make you decide this is not what you are looking for, good — better now than in three months.
What you can check about us without us
Five things you can verify yourself before talking to anyone.
The free cognitive test
Open to everyone, no account. In about seven minutes you see how we approach measurement and how we talk about results.
Our texts about the method
We describe the techniques in enough detail to use them without us. A school that keeps its method hidden until payment has a different model.
The limits, written down
A separate page about what the method does not do. Worth comparing with what others promise.
Concrete conditions
The length of a class, the size of a group and the ages of the students given as numbers, not as slogans like “affordable”.
Reviews of a school by the same team
Space Memory and Indigo Mental Club Polska, a mental arithmetic school, were created by the same people. It is a different school and different classes, but the reviews of it are public and we cannot edit them: Indigo Mental Club on Google Maps
The conditions we are asked about most
Briefly, and without slogans.
| Condition | Details |
|---|---|
| Classes | 90 minutes once a week, online, a group of 5–10 children |
| Timetable and terms | The manager will tell you when you leave a request |
| Before you decide | A free trial lesson before you decide |

Where these reviews come from and what they leave out
All of them come from our Google Maps listing — the listing is Polish, so the reviews are in Polish too. We show six rated 4 and 5, one per person, no one-liners — the full list with every rating is on Google. We add nothing of our own and remove nothing inconvenient. Separately, we collect reviews from parents with explicit consent to publish, with a name, a context and a date; they will appear here once there are enough of them not to be a selection of the prettiest sentences.
Google reviews
Rating and review count exactly as on Google. We show parents' reviews from Google Maps; the full list, including lower ratings, is one click away.

Rating as of September 27, 2026. Below are reviews rated 4 and 5 stars; the full list is on Google. The Google listing is our office in Warsaw — no classes are held there; all classes are online.
The Space Memory classes with Mr Bartosz are great. My daughter praises them a lot and can't wait for the next one. Mr Bartosz is the right person for the job. The children are delighted. Best regards
My son has classes with Ms Marta. He is very happy, joins the classes willingly, and I see progress in memorising. Ms Marta keeps in touch often and takes suggestions into account. We recommend Ms Marta 👍
A great course, my daughter is happy. You can see the progress. She joins the classes willingly and really praises the lessons with coach Bartosz.
My daughter has classes with Mr Bartosz and is very happy. A great teacher: his classes are interesting, he knows how to motivate and he appreciates the students' efforts.
My daughter is very happy with the classes with Mr Bartosz. The classes are interesting and everyone gets a chance to speak. The atmosphere is pleasant, and the teacher explains things well and checks that everyone understands.
Highly recommended! My children love these classes, and as a mum I'm calmer seeing how willingly they sit down to study and don't stress about school.
Questions before signing up
Where can I find independent reviews of Space Memory?
On our Google Maps listing — all of them are there, including the ones we don't show on this page — and in places we have no influence over: parent groups and a conversation with someone who has been with us. You can also ask us for a parent's contact — if someone agrees, we'll connect you.
Is the trial lesson really free?
Yes, and it needs no card details. Leave a request and a manager will suggest a time after a short conversation about the child's age and level.
What if the child does not like it after the first month?
We discuss the terms of stopping before you sign up, not after: there is no year-long contract, and you can stop at the end of the month you have paid for.
Do you guarantee better marks?
No, and we think no school should. We can answer for what we teach and how we measure progress — not for a mark given by someone else.
How many children are really in a class?
Between 5 and 10. If a group drops below five, we merge it with another at the same level and tell parents in advance.
Are the classes in English?
There are no English-language groups at the moment; the language depends on the group, and a manager will confirm it. A child stays in one language group.
