Good! It happened on a practice test and not the real thing. This is exactly why you take practice tests.
I know you're not thrilled, of course, but you are learning what NOT to do, and that's really important. I've talked to a lot of students who have messed up the timing badly on the real test - vow not to be one of them. :)
Given what you described with the timing, my guess is that the score you received is pretty seriously deflated - 50 to 100 points. Now, that doesn't mean that your true scoring level is already that much higher, because of course timing is a major issue, but it's eas
ier to improve from a 480 to the 700 range if a big part of the initial problem is simply timing. (And that doesn't mean, of course, that it'll be
easy.)
So. Timing. First, you need to change your mindset. From now on, this as a tennis match, not a test. You're going to win some points and the other guy is going to win some points; you're not going to win them all, right? Your goal is to put yourself into position to win the LAST point. Translated, that means you have to put yourself in position to answer the last question - you have to have time to address it. Otherwise, you've lost the last point, and by extension the match. When the other guy hits a winner, don't go running after it so fast that you hit the fence and injure yourself, thereby hurting your chances on the later points. (Translation: don't go way over when the problem is too hard.)
And you will ALWAYS hit problems that are too hard. It doesn't matter how much you study - they'll just give you something harder. That's how an adaptive test works.

I think you would also benefit from a timing exercise: learning about how long one minute is without looking at a watch or stopwatch. If you don't have one already, buy yourself a stopwatch with lap timing capability. When you go to do a set of problems, start the stopwatch but turn it over so you can't see the time. Every time you think you're one minute into a new problem, push the lap button. When you're done with that problem, push the lap button again, then repeat the process for the next problem. When you're done with the set, see how good you were - and whether you tend to over or underestimate. Get yourself to the point where you're within 15 seconds either way on a regular basis (that is, you can generally predict between 45 sec and 1min 15 sec). Also check your timing for the entire question, of course.
Now, how do you use that when doing problems? If you're not on track by one minute*, make an educated guess** and move on. (The general idea is that if you're not on track by the halfway mark, you're unlikely to figure out what's holding you back AND have time to do the whole problem in the 1 min you have left.)
* For SC, 1min is well beyond the half-way mark (we're supposed to average about 1m15s here), but you can almost always eliminate at least some choices on SC in that timeframe. Once you've got that "I'm around the 1min mark and I'm struggling" feeling, go through any remaining choices ONCE more. Pick one. Move on.
** This also requires you to know HOW to make an educated guess depending upon the type of problem and the content being tested. So that's something else to add to your study: how to make educated guesses on different kinds of problems.
Here are two articles that can get you started on educated guessing:

And pay HUGE attention to the timing. Know where you have strictly timing problems (I can get it right but I take way too long) and where you have timing + content problems (I'm taking way too long and I'm getting it wrong anyway). Then address what you need to address when you get to that area during the course.
Use this article to analyze your test so that you know what those strengths and weaknesses are:
