In ninth grade, Yohai returned to Reali school. He decided that he preferred a program with more sciences. He didn't
think the math in the gifted pupils' program was creative. Back at Reali, he found some friends he'd started school with in the first three grades.
Yohai's interests in cats and turtles continued; he wrote about them with humor. Often he invented words that only he knew. He wrote skits,
adventures, and programmed some on the computer. On his own, Yohai studied the math and English of the psychometric exams, usually taken at
the end of high school as entrance exams for the university. He made up a psychometric exam of his own, with many comic elements, but intellectually
challenging. This is one of the works on the Hebrew version of this site.
