I took Latin in college (having not taken it in high school), and found the Wheelock text book pretty helpful (https://www.amazon.com/Wheelocks-Latin-7th/dp/0061997226 ). If you're looking for Latin texts, check out the Perseus Project (http://www.perseus.tufts.edu/hopper/) and the Latin Library (http://www.thelatinlibrary.com/).

If you get stuck on something, swing by the Latin StackExchange (https://latin.stackexchange.com/).
