Reading Comprehension

hello bothers and sisters of this GMAT religion...

it´s said and suggested that for CR and RC it´s good to prephrase the passages and texts... my "international students" question is :
- is there a trick for that (specially for foreigners non native english speakers) since we have to read (fast), understand (sometimes we need to read 2 or 3 times) all in a very short time ? where would we have time to write notes or how can we do that in a fast way ?

thank you for your suggestions and advise...

big HUG to you all
