It doesn't matter. I did physics at a world top 10 university and the course work was basically day care. The vast majority of the 'difficulty' of the subject matter was because the majority of students were bad at algebra. The outcomes would have been better for everyone if we completely ignored first year and just taught people the Knuth Bendix algorithm instead.
