Tests are graded from an easy confidence-builder (Test 1, free to try in full) up to genuine ICAS-level challenge questions by Test 15. Here's one of each:

Sample Question — from our free Test 1

Tim has 23 red marbles and 15 blue marbles. How many marbles does he have in total?

A

38

Correct! Adding the ones digits gives 3 + 5 = 8, and adding the tens digits gives 20 + 10 = 30, making 38.

B

35

This value incorrectly counts the tens place as 20 and misses 3 ones from the 23 red marbles.

C

48

This value miscalculates the tens position by adding an extra ten.

D

8

This is the result of subtracting 15 from 23 instead of adding them together.

Sample Question — Hard tier (Test 15)

The scores in 5 games were 10, 18, 19, 24, 9. What was the average score?

A

80

This is the total of all the scores, not the average.

B

24

This is the highest score, not the average of all the scores.

C

16

Correct! Add all the scores (80) and divide by 5 games: 80 ÷ 5 = 16.

D

17

The total was divided incorrectly — recheck the division.
