How to approach Central Ideas and Details questions

Main idea

MINDMAP the KEY POINTS of the text, from start to end.
Turn them into a STATEMENT before you look at the choices.
It is THE WHOLE PASSAGE PUT TOGETHER that gives you the answer. Do not be obsessed with a single part.

Details

This type needs a VERY SPECIFIC understanding.
You DON'T MAKE THINGS UP. You invent details only BECAUSE YOU FAILED TO COMPREHEND.
It is ALL GIVEN IN THE TEXT. The answer is MERE PARAPHRASING.
The hardest questions give the detail SO SUBTLY that they demand the MOST PRECISE understanding. THE INFORMATION IS STILL ALL THERE.

The habit that ruins students on this type

Students make things up. A detail they invent is a detail they failed to comprehend.
