Others have given the right answer several times over, but there are still some nuances that I would like to hit.
Most importantly I would say: IQ tests are neither administered by the post K-12 academic community nor used for them by any purpose.
They are -- sometimes, anyway -- given to children to identify them as being eligible (or not) for certain "Mentally Gifted" programs. In this way, I took an IQ test when I was seven years old. I did it because my best friend had taken one and got to spend one day a week in a special "MG" classroom. I walked by the classroom one day and -- well, this was a while ago, but the way I remember it, I saw a big room which did not have individual student desks and a bunch of kids milling about in it. I knew it was the MG room because my friend was there. Some other kids placed a crown made of brown construction paper on his head, and he was grinning from ear to ear. So I asked my parents to arrange for me to take the test, took it, and some of my other friends followed suit and got to spend one day a week with a special MG teacher doing much more fun stuff. Sometimes it was on the brainy side: I remember learning about prime numbers there, for instance. But there was also a bit of what I would identify now as a Montessori-style emphasis on manipulating and building things. I did this in the second through the fourth grades, then I went to a different middle school with no such program, and then when I went to my high school those same test results allowed me to take a few special "MG" courses, including creative writing. (Looking back on this it all seems a bit unfair.) They also kept our test records in a big file cabinet in the "MG room" (as before, a fun place to hang out), and one day when everyone else was gone, I decided to sneak a peek. I remember being a bit disappointed at my score: I think it was in the 130's, just like the OP.
Once someone is a college or university student, I see no point whatsoever in taking IQ tests: rather famously, the academy administers plenty of tests of its own, which we largely do believe determine students' potential and suitability for future study. Should you get a PhD in math or physics? Who cares what your IQ is: assuming you went to a partway reputable institution, what matters is how you did in your coursework there. Wondering how you'll measure up against other ambitious aspiring mathematicians? Take the math subject GRE. This is not telling you everything -- and certainly, whatever it's telling you should be calibrated against your prior training and education -- but it's telling you a lot more than an IQ test, and whether you believe that or not, many graduate admissions committees do.
I feel like a few of the other answers are assuming that IQ is measuring how "academically smart" you are. I really don't think that's the case at the tail end of the spectrum that you're talking about. I mentioned my IQ above: it's in the top 2%, I guess. (Allow me to omit the ritual reading of the CV, but:) My academic intelligence is considerably higher than my IQ test would indicate. By this I don't mean to imply that the IQ test "got me wrong" or anything like that: my spatial reasoning skills are average at best; I have never completed a crossword puzzle in my life; I am only moderately quick at solving the kind of logical puzzles that appear on the LSAT. But I have a big vocabulary and can read and write quickly and well; my memory becomes much sharper and clearer on anything academic than, say, political or financial matters; and I can learn and do mathematics quickly and easily (relatively speaking, of course: if the famous plastic philospher had actually said "math is hard", she would still have gotten in trouble but she would not have been wrong).
So I want to be honest and say that I do believe in academic intelligence -- though I heartily agree that it is not everything, and again in a certain tail end of the spectrum it ceases to be very important -- but I just don't think it's the same as having a "high IQ". I think that the probability of academic success of anyone with an IQ of, say, 125 or above does not depend on their IQ in a meaningful way. It's really one of the last things you should be thinking about in making a career decision of this kind.
