Anforme logo redesign

Currently trying to redesign the logo for the company I work for (Anforme Ltd). The originals not great (in grey) and I have to stick to that design as a template (our website is run by another company so would cost too much to change graphics). So I'm attempting a re-brand so I can create a style guide. It's an educational company which creates resources for school subjects. Although we ship worldwide I thought the world icon was abit irrelevant so went for a tick as in correct answer (i.e you will pass your exams). Any feedback appreciated.
