If you’re making careless mistakes, then you’re probably having difficulty with your time, & that’s a very easy thing to fix. What I do is I do the easiest questions first(which are usually the smallest questions) & then I do the harder ones. 99% of the time I use this I have at least 5 minutes left to check my answers. And you should defiantly keep trying for a 36, there’s a big difference between those 2 numbers. Good luck!
