this is a bit of an oxymoron, as you can not cram for the SAT..

but.. you do want to avoid emergencies and stress

1. have your paperwork and credentials ready
registration ticket &  Picture ID

2. Power up your calculator
3. bring drinks and snacks for the breaks
4. stay sharp – do you have your pencils ready?
5. your essay – do you have your word and quote lists?
6. directions – do you know where you are going if the test is not at your school?
7. Timing – be there on time!!  prepare to be there until at least 1pm.
