Don't worry about test/challenges that are supposed to take X hours. That figure is more of a magnitude than specific time. I mostly spend 3*X on those I have looked at, and have mostly got through to an interview and offer afterwards. If you spend every evening in week on a 2 hour challenge then maybe it is an issue (or just a badly described test), but spending two or even three evenings on it is fine.
