I'm sorry you're struggling so much with the test.
It sounds like you learned how not to run out of time, but I do wonder whether you're making those decisions in the best possible way. I see a certain pattern a lot, so I'm going to describe it here and you can tell me whether it might fit you.
People who find themselves running out of time at first will still often spend extra time on things that are too hard. They'll learn to "catch up" by going faster on the things that they know how to do.
The problem here is that the extra time spent on "too hard" things doesn't help your score, while speding up on things you do know how to do results in careless mistakes, pulling your score down.
Could that be going on with you? The above is the single most common way that people try to fix "too slow" timing problems - and it results in a stagnant score.
Here's what actually needs to happen: You need to cut yourself off faster on the ones that are too hard - actually learn to let them go. You then spend "normal" time on the ones you do know how to do. You don't cut corners, you write down your work, and you learn how to minimize careless mistakes.
Why is this the fix? First, read this (right now):
https://www.manhattangmat.com/blog/inde ... lly-tests/Is that how you've been making your decisions about where to spend your time (and mental energy!)? Or have you still been prioritizing trying to answer things correctly (and wanting to answer harder questions correctly, in particular)?
What about this (again, read right now):
http://www.manhattangmat.com/blog/index ... -to-do-it/How do you react when you get the "but I studied this" feeling? Do you actually cut yourself off right then? Or do you sometimes (or often) keep going?
I suspect - and you tell me whether I'm right - that you might not have made the mindset switch discussed in the above articles. If so, then your score would be likely to stay right where it is even as you're learning how to do more.
Do you think this might be part of what's happening?
If so, first remember the material in the first two articles I posted above.
Then, read this:

And are you actively working to minimize careless errors? Here's how:
