<p>Its all so individual. I know someone who was accepted in junior year and has adjusted just fine. It all comes down to your maturity and circumstances. You have nothing to lose by applying this year. Explain your reasons and circumstances. The worst that happens is that you reapply the following year.</p>
<p>It sounds as tho you have many classes still available to you in HS.If your motivation is to leave home, you could apply to honors program in state U. You could also find something interesting to do for a GAP year. I’m not recommending the latter. I think you can never be too prepared for caltech/mit</p>
