If you took an official IQ test from a qualified professional, the person who administered the test should have interpreted and explained the results to you and your parents.
Because this apparently did not occur, it makes me wonder whether your test is reliable. However, assuming it is a reliable test…
The average IQ test score, regardless of your age, is 100. The average range is approximately 90-110.
If your IQ is truly 127, that is very good… indicative of intelligence sufficient to do pretty much anything you want to do. However, work habits, interpersonal skills, and personal characteristics such as perseverance and whether you enjoy studying are equally important, so remember to work on those skills as you go forward.
My niece has an IQ of 90 and is a very successful nurse practitioner. Her brother, my nephew, has an IQ of 135 and chooses to manage the copy shop at Office Depot; he doesn't like stress.
It takes the whole package to achieve great things...
