It likely makes the scores​ higher on tests, though not necessarily because they've learned the material better. Anecdotally, I've seen recent immigrant children struggling to understand user interfaces (that I would argue were poorly designed, not that it matters to anyone caught in the bureaucracy) that more computer literate kids "get" immediately. The struggles with UI, such as kids literally spending dozens of minutes trying to get to the next question, undoubtedly exhaust and frustrate them. One can only guesstimate the effect on test scores but it can't be positive. More exposure to a variety​ of software/UIs seems to matter.
