I'm guessing the context is that you complimented her English or mentioned her English skills, and she did the typical "No. I'm not that good!" reply or simply she's honest/humble/modest (Read this thread if you're not familiar with the typical Japanese reply to compliments). If that's the case, what she meant was "Thanks. But, you know, I only passed the second level on Eiken, and my TOEIC score is, um, like 600... (implying passing the second level and getting 600 are not that great)."

This kind of Xあるかないか roughly means "the number/score/whatever is approximately X" and is used especially when the speaker doesn't think X is many, large, enough, good or something along those lines. For example, if someone asks you how much money you have in your bank account and if you reply, "さぁー、１００円あるかないかも怪しいな。," it means "Hmm. I don't even know if I have 100 yen in my bank account."

You can replace the verb ある so it can be used in various situations, e.g., せいぜい一日に一人来るか来ないかぐらいです。(あるかないか -> くるかこないか, We only have one or two customers per day at best.)

Another example is 私のクラスには、生徒は１０人いるかいないかぐらいです。(There are only about 10 students in my class.)

You're splitting up the sentence wrong. The pattern is "あるか、ないか”
Meaning "aru" as in "arimasu"
And "nai" as in  "arimasen"

So literally it's "600 points aru ka, (600 points) nai ka".
This basically translates to "whether or not you get/have 600 points".
