Hi, I just finished Intro to Chemistry for todays health. It wasn't that bad just alot to study and remember. We really didn't have to memorize the elements it was a combination of everything, protons, electrons, neutrons, formula weights and knowing the different kinds of bonds e..g. polar,(water) non-polar (gasoline)and it does involve alot of math or atleast mine did. We'd have to know the names of elements put together e.g. N20 ..dinitrogen monoxide ( uses a prefix because it's 2 nonmetals. A metal and a nonmetal end in (ide)If i can do it after being out of school for 15 years and being a math dummy anyone can do it, just make sure you sit in front of the class, ask questions, even stay over an ask if you don't know something, MOST IMPORTANT don't miss a class because when you go back you will be lost. You will do fine, it's kind of fun too.
