I'm interested in taking a class in business or economics or
management(or maybe two classes), part-time while spending a few
months in London from Feb.-July. I know they have summer classes at a
few places here, but ideally, it would begin sometime in February and
last a few months.

Also, ideally, it would be a top-notch university. I know LSE does not
offer separate classes like this, but does University College of
London or King's College? I'd also enjoy taking such a class at a
graduate school.

FYI, I already have my BA from a top-notch school in the US if that
would help my chances.
