is 'interest class' ambiguous?

[mortal knot]

Interest class means '兴趣班' (some class you are interested in) or '利益阶级' (interests of some class )?

[urban carbon]

It means "兴趣班"

[green moss]

兴趣班 just use this lmao

利益 means interest as in profit and use

[bleak meteor]

i've never heard 'interest class' used in english

兴趣班 = elective

利益阶级 doesn't make sense either. it's XX阶级的利益.
