How can I study for my big upcoming test?

I’ve been studying almost all week, and I have a big Geo test tomorrow. The teacher gave us a study guide last week that is exactly the same as the test. I answered all the question’s on the guide, so I thought, all I have to do is memorize the answer’s I wrote down.

But it’s not so easy. I have a hard time retaining the information, and usually forget it all the next day. I keep getting distracted, with other responsibilities, and this test is important. How can I study properly for this?
