①The academic ability is a school record.
It is a basis of university`s study.
②Many companies want a student who has good experiences.
And, that student is a experienced person.
③Rich students can study abroad or do some special activities like a volunteer.
The other hand, poor students can`t do such activities, and they have to get a part-time-job to earn the tuition fee.
④It is true that pert-time-job is a good experience for students.
But, students can do it any times. And, the main purpose of students is study.
So, poor students don`t need the gap term.
