test yourself more??

Ok, i tried all the mockups and samples, I scored high 60s and low 70s, so I think I am in the borderline. I also studied some more in the past couple of days, are there anymore tests to see if you have any improvement? thanks

Go back to studying, that’s what improves you score, not taking more exams. There is still time to memorize a couple of formulas and understand couple more concepts.
