We have about 3 full weeks of instruction time left in the school year and my mind is starting to switch gears to finals mode.  As I start to tie up loose ends and bring the semester to a close, I am curious of different review techniques that anyone may use to help prepare for finals.  Does any one find certain strategies more effective than others?  How many days do you set aside for review for your finals?

On a side note, in chemistry, there is a lot of lab equipment to be aware of.  Do you do any kind of lab practical test to go along with you final?  If so, what does it consist of?

Any and all help would be great!
