PT is the same with better accuracy

Yesterday i took my second PT where my score went up by 1. However, my accuracy for 4 star and 5 star went up (40% and then 8%, respectively). My other percentages were largely the same. Any tips or guidance on just how I ended up at this point and potentially. Is there a way I should study? Did you encounter a similar problem? If so, how did u get out?

Not very happy with my score, but im happy my understanding of the harder questions went up (in this PT there were more 5 and 4 star questions as well) PLS LMK I could use the help
