This depends on whether you think you have the maturity and emotional intelligence to enter the workforce or university earlier than your peers. High school is the last stage of your life when you can make an excuse that you're just a kid and your mistakes and faults won't have any significant impact in the long-term. Even if you were charged for a crime now, arrested, and convicted, the sentencing would be far more lenient because you are not 18 yet and still a young adult. The stakes become much higher for you once you turn 18 and leave high school and enter the real world. So, the answer to your question comes down to whether you are prepared to enter the real world, and what that looks like for you in terms of work, travel, and post-secondary studies.
