dear go for caravan general general knowledge by chodhry najib, and caravan aptitude test for basic arithmetic by choudhry najib and encyclopedia of general knowledge by jahangir success series. daily dawn is necessary to cover various current issues. where as dawn also helps in improving vocabulary. but one should have his/her own book (exploring the word of english by saadat ali shah) in order to improve English grammar in a comprehensive way.. and yes internet Wikipedia is also a major and easy source to improve all type of knowledge.
NOTE: CARAVAN GENERAL KNOWLEDGE AND CARAVAN APTITUDE TEST ARE TWO DIFFERENT BOOKS OF ONE AUTHOR( CHOUDHRY NAJIB).
