She was getting 790/800 in the CB practice tests, multiple tests, the week before taking the SAT. But the nerves got the better of her I guess! She says that she took more time on a chart question which ended up with her skipping a couple of questions and rushing through a couple more!
Any other test taking strategies or tips that she should remember?
