What's the difference between graduate training camp and graduate boarding?

Training is generally an intensive course for a period of time.

Boarding is where you go to live.

Boarding generally has no classes.

Equivalent to renting a house

These two kinds are mostly deceptive.

It doesn't make sense.

This is a waste of time and money.

It is good for freshmen to study by themselves at school.

You can watch online classes.

It is even more meaningless if the former students were World War II.

Because I passed the exam once, I know where the key points are.

Listening to this basic course again is a waste of time.
