Read
Understand the question.
Read the whole question before touching the pen. Most lost marks in SAT and EST Math are not caused by weak Math — they are caused by answering a question that was never asked.
In practice
- Read once for meaning, once for detail
- Underline exactly what is being asked for
- Notice units, restrictions and the words "not", "least", "must"
Common mistake
Starting to calculate halfway through the first read.
