Built by a mom who learned the hard way
SigmaBudgie started at my own kitchen table — with a disappointing test result and a promise to do better.
SigmaBudgie started at my own kitchen table — with a disappointing test result and a promise to do better.
I'm a computer science PhD, a former Google software engineer, and a mother. Like a lot of parents, I found myself preparing my child for the ISEE Primary — and I learned the hard way that not all practice actually gets a child ready. This is the tool I wish I'd had.
Last year, I prepared my child with a well-known test-prep site. On its practice tests they scored 95% and above — again and again. I felt ready. Then they sat the actual ISEE… and scored around 60%. My child was not admitted.
It was a hard lesson. When I looked closely, the reason was obvious: the practice had been too easy. The actual exam is built on reasoning and carefully written trap answers — the kind of question where every choice sounds right until you read closely. Comfortable practice scores had told me nothing about how they'd do on the day that counted.
Every SigmaBudgie test is modeled on the ISEE Primary in format, timing, and difficulty — no filler, no easy questions padding the score. Wrong answers are designed the way the actual exam designs them: plausible until you reason it through. The goal isn't to make your child feel good on practice day. It's to make the actual test feel familiar.
I built it first for my own child. I'm sharing it because I think other families deserve to walk in genuinely prepared, too.
