Omitting は when the topic did not change


I am on Dr. Kim's Japanese site and want to make sure that I have this right.

Am I correct in understanding that as long as the topic of conversation does
not change, は need only be used once in a dialogue or paragraph?

For example, a conversation might look like this:

> 彼女は(topic defined)大校生ですか？
>
> ううん、(topic did not change)高校生です、僕は(now it is about me)大校生です。
>
> (Is she in college? -- No, she is in high school, but I am in college.)

Do I have that right?




The particle は is primarily used to define the subject, and in that use, you
are right that it is very common to omit the subject in the following sentence
if it is the same.

It's not wrong to repeat the subject (eg. 僕は) explicitly, for example if a
sentence is long, if there is room for confusion, or if you want to place
emphasis on the subject.
