Spidey - maybe you just need to find out what your best learning style is. Here is a snip from
https://www.howtolearn.com/personal.html
"Visual learners can do this all so quickly that it's hard for other kinds of learners to understand how they do it. And it's harder yet for parents of kids who are not visual learners to understand what it is that's causing their child to get lower grades.
This all sounds so simple; yet, other kids, with different learning styles like auditory or tactile/kinesthetic, don't do what visual learners do naturally. It's not because there is anything wrong with them, it's just that no one's analyzed exactly how schools are set up, or shown them how to add the visual learning style traits they need to succeed in school."
After I discovered my learning style - right brain, visual = then taking tests was much easier for me.!
