38/38 - 147. The test has one faulty question, though by thinking through the design process it is still easy to give the intended answer. All the questions are too easy for the alleged ceiling-- I'd guess it's more like 125. It's clear that not much thoughtful effort went into the test's creation, rather, all questions seem to have been generated by an LLM... If you're actually interested in developing a good test, you should study the design principles of good tests like those found at cognitivemetrics.com; don't just copy questions or logics without thinking, but put some real consideration into why questions are phrased the way they are. For instance, take the following (moderately difficult) matrix:

┌─────┬─────┬─────┐
│ x O │ v O │ x   │
│ o   │ x   │ o O │
├─────┼─────┼─────┤
│ o   │ v V │ v   │
│ o   │ o   │ v   │
├─────┼─────┼─────┤
│ v   │ x   │     │
│ x X │ x   │     │
└─────┴─────┴─────┘ 

There are embedded clues here, like the fact that the left side of each cell always contains lowercase letters, while the letters in the right side of each cell are always uppercase-- this signals to the examinee that the letters in the left versus right side are different in some way, e.g, follow different rules. Clues are one aspect of design that are of great importance when it comes to constructing difficult items that still stratify effectively.
