College courses and degrees are typically assessed based on credit hours.

大学的课程和学位一般是由学分小时计算。

She was taking only 13 credit hours, and yet was " too busy" to work.

她只上13学分的课，但竟然“没有空”去打工。

You know, there's nothing natural about credit hours and multiple choice exams and so on.

学分和选择题考试等等都不自然。

Credit hours can also give us a sense of how much time we can expect to spend working outside of class.

学分还可以让我们知道我们可以花多少时间在课外工作上。

Ultimately, major courses and Gen Eds are helping us chip away at the total number of credit hours we need to graduate.

根本上，主修课程和 Gen Eds 正在帮助我们减少毕业所需的总学分数。

One credit hour is equal to one hour inside a classroom and two hours outside the classroom, completing assignments or studying.

1学时等于1小时的课堂内和2小时的课堂外学习时长，要用来完成作业或学习。

Of course different classes require different amounts of work, but credit hours can be a useful gauge for managing your time each semester.

当然，不同的课程需要不同的工作量，但学分小时数可以是你安排每个学期时间的一个有用的衡量标准。

So, if a student is enrolled in 15 credit hours, they can expect to spend 15 hours a week in class and 15 to 30 hours per week on classwork.

因此，如果一个学生报名参加了15个学分的课程，那么他们可以预期到每周要花15个小时在课堂上，花15到30个小时在课堂作业上。

If you're in a trade school or in certain degree programs that require hands-on training, credit hours can also include internships, which are roughly 160 hours a semester.

如果你在一所职业学校或参加需要动手训练的学位课程，学分还可以包括实习时长，大约每学期160个小时。

Credit hours are like the experience points of college courses — each course is worth a certain number, and they indicate how many hours per week students will spend in that class.

学分时数就像大学课程的经验点一样——每门课程都有一定的价值，它表明学生每周在这门课上花了多少小时。
