Hello, there are alot of online sites that are very good. The one I recommend the most is Aleks.com. Its a progressive website learning program that gives you a test to see where you are and then will help you build on what you do know. Only catch after the initial i think 36 hr pass there is a fee. If your willing to pay it is more than worth it. There are alot of free websites too like math.com that are pretty good aswell. I dont remember the entrance exam so much but for pharm math and the math portion of school in general was basic addition, subtraction, conversions of decimals into percentages, adding subtracting multiply and dividing fractions, and converting measurements. I know it seems like alot but as long as you have the foundation it will simply build on each other. Thats why I recommended the first web site because that is exactly what that site does. Good Luck!!
