I know you have a good “feel” about percent- everyone should with all the percent ads we see like 50% off a pair of old socks! Anyways lets get serious about percent because you need to master the topic to excel at math and algebra- and shopping. After you learn how to find the percent of a number start working on solving more complex percent problems- as you do life will get better and so will your grades. Good luck amigo!
