I think you did fine. You were in the same situation as me. I, too, studied for about 4 months while working full time. I know how much that sucked! But now it's over - relax a little bit.
If you're anything like me, you're freaking out about your 17. Don't. I applied this cycle and got 7 acceptances. I think you'll be okay - just apply broadly and as early as you can.
