My head's about to explode...

Can someone please point me in the right direction to find practice test papers for Financial Accounting? (Balance Sheets, Income Statements, Statements of Returns on Equity, Cash Flow Statements, Depreciation, Ratios, etc. etc.) Assorted business schools worries inside. Coming from a liberal arts academic background, I'm starting to really feel the pressure from my recently-started international business masters and get the impression I need to study ten times as hard as my classmates, most of whom have studied the subject at undergraduate level. At the moment, I'm fretting over Financial Accounting. Please help me to understand this subject! Extra points for whoever can help me with Corporate Finance... I was never strong at mathematics in school. Though I'm pretty good at mental arithmetic, I found the subject boring and didn't pay attention in class. Now I'm faced with the daunting task of getting to grips with Corporate Finance and have some decent books to help me, all of which cheerfully claim that the author needs no prior knowledge of Finance, just a knowledge of algebra! At the risk of appearing extremely dumb... I can't remember any algebra! What do I need to learn in order to understand the nimiety of equations by which I'm beginning to feel very overwhelmed?
