什么区别:on-line/in campus VS full time/part time

问个比较傻的问题, on-line (又叫什么distance degree) . in campus learning 与 full time/part time 会产生4种组合,对吗?

on-line or in campus depends on where you get the learning, and full time/part time depends on how many credits(courses) you enroll in semester , correct ?

4种组合:
1.> in campus + full time ---- most of the students here takes that way.....
2.> in campus + part time ---- e.g. as some US folks (similar to China 在职) only takes some courses per semester in campus , especially for US folks who lives in the city where the university locates...at the same time, they also take their original jobs......
3.> on-line+full time ---- (当然前提是课是可以remote学的)
4.> on-line + part time --- similar to 3.> , diference is it goes with less credits than 3.>

有身边的朋友对于后三种的介绍或意见吗?

Thanks.
