My 1st attempt - Though I do my best to guess the answer, I've found it best to just go through the first couple of times without really knowing or getting it all perfect.

Using google and mw.com to research any terms or people that are new or that interest me helps (usually it's opened in new windows, so I can read after or while I study by instantcert).

On the next "go-throughs" - type the answer.
If I forgot or answer incorrectly, type the correct answer in the box on the explanation page. This helps me remember it better next time.

Repeating the questions and answers aloud, to myself sometimes keeps me more focused which aids absorption of the material.

I repeat and repeat until I know the material well. The test is usually scheduled during this process - when I can tell I will pass or I know I'll study enough to pass. Being goal oriented, sometimes I schedule the test and THEN study. Just for motivation. What??? I like to panic! Kidding!

I go through Instantcert with whatever time I have - 1 hour today, 3 hours tonight, etc.

PS. People remember what happens at the beginning and the end of an event or story. I give myself frequent breaks (every 20 or 30 minutes) to increase the chances to remember.
