How many weeks until the test?
Your child's first climb, done right.
The ISEE Lower Level is the version of the ISEE taken by children applying to grades 5 and 6. Glentavo turns the weeks you have into a plan: a practice test, then short practice sets based on it, then the next practice test — with a report for you every week.
Free. Your child answers 20 questions, you tell us the test date, and we show how many practice tests fit before it. 20 questions are enough to choose a route — not a diagnosis, not a ranking.
Fall testing season: August–November. The ISEE is offered in three seasons a year, and each child may take it once per season.
One practice test, five practice sets, the next practice test.
- Practice test
- A complete mock ISEE Lower Level, taken at home on a computer or an iPad turned sideways. It follows the published sections and timing of the real ISEE Lower Level: four scored sections and a 30-minute essay.
- Practice set
- About 20 questions, picked from what the last practice test showed.
- Cycle
- One practice test plus its five practice sets. Your plan is as many cycles as fit before test day.
What a plan gives you
Where your child is now
After every practice test: how many questions your child got right, missed and left blank, in each section and each type of question.
What to do next week
Five short practice sets, picked from what the last practice test showed. Your child sees one task at a time.
Whether it is working
Each practice test is compared with the last one, on the same measures.
Less for you to arrange
A calendar to test day and a report every Sunday. You do not have to plan each day yourself.
What your child sees
Your child's screen shows only today's task and a mountain they climb as they finish tasks — never scores, rankings or prices.

Every Sunday, one report
The report starts with what got done, then what changed, then what is next.
This week: 4 practice sets done, 1 h 50 min.
Practice test 2, Quantitative: 38 questions, 27 correct (up 5 from test 1), unanswered down from 6 to 1.
Next: practice test 3 on Saturday.
Three packages
The difficulty is the same in all three. What changes is how many practice tests are included.

What we will not tell you
A predicted score.
At launch, reports show what your child actually did. If our practice tests prove accurate against real results, we will add score ranges — always with the basis shown.
That your child will get in.
Glentavo does not promise admission outcomes.
That we speak for ERB.
