Read until you're tired of reading . There is no set limit of pages, but if you insist on a number, 25-30 pages a day will help. However, the more you read, the better it makes you whole life in many many ways.

I read at about 70 pages a day, sometimes more depending on the text size and what I'm doing.  My comprehension skills are one of the best in the grade (9)- not to boast
