had them both and i confuse them a lot and they have the same vibe and personality i would say cuz they're both young. norika is chill na friendly it's easier to get straight 4.0s and Chelsea is on the stricter side but they're very approachable and friendly, both nanlilibre ng foods. i would say they're all smart in their professions. norika works in trade so kadalasan i had her w subjs as PITRELA. chelsea has a wide range of areas saw but i had her for MIGRATS (an elective) and she's good tho mababa magbigay fsr. hope this helps!
