I work part-time to pay tuition while attending college. I guess you'd call me a struggling student.

Literal

Part-time-job [with-で] tuition [object-を] earn [while-ながら] college [to-に] attending. Well, struggling-student [called-ってとこ][wonder-かな].

バイト is clipped from アルバイト (German 'Arbeit'). 苦学生 'struggling student' — 苦 'hardship' + 学生 'student,' one who works to fund their own education. ってとこかな 'I guess you'd say something like' — a casual self-classification with a hedging tone.
