Greetings, 

Shiva ,first I would mark down the syllabus for GGSIPU CET MBA 2019 and then would recommend some books based on every subject mentioned . 

ENGLISH                       25%

GENERAL AWARENESS   25%

LOGICAL AWARENESS      25%

APTITUTE RELATED TO THE FIELD OF MANAGEMENT AND FOR COMMUNICATION SKILLS 25 % 

 Take help from previous years paper of various other entrance exams like CLAT , SSC, CAT , CMAT, IBPS, NDA , NIFT ,NID AILET ,MAT,GMAT, XAT etc. ( you will find a bundle of questions that you can practice daily) . Your main focus should be to find and analyse logical reasoning ,English , quantitative section from these papers . 

A constant regularity should be maintained for ENGLISH SECTION  ;read editorials from Indian Express or The Hindu; make a notebook for difficult vocabulary and find their meaning everyday ; try solving error correction from various entrance exams mentioned above . You will find their previous year papers on various sites  ( try SSC previous year papers because they have the most number  of  papers in a year and are easily available online ). If you are finding it difficult to score in  grammar you can go through the concept from books of English of someone who is studying in school .It will help you because of the kind of detailing that will provided  in that book.   

Do not stick to only GGSIPU CET MBA previous year exam paper because the syllabus of many entrance exams are very similar to this entrance exam ; entrance paper of any of the exams conducted by GGSIPU are not available anywhere online ( you will only get 2-3 sample paper ) .So try books Arihant's Success Master IPU CET provides you with solved paper of only 4 years if you want to get a clear picture of how the paper pattern will be then buy it . 

To  score in QUANTITATIVE SECTION  first try clearing  your doubts and take help of RD or RS Sharma of 9th and 10th standard, try Google Books or Pdf's of specific book. There are many quantitative reasoning books in Google Books with solutions  if you do not want to buy books. Try You tube videos for difficult concept . 

For GENERAL AWARENESS try Competition In Focus magazine's weekly edition and download 1 or 2 general awareness app ; you can also subscribe  You tube channel of weekly or daily updates for general knowledge of some good newspaper site (The Hindu , Indian Express , DNA etc) , in this way you will find it inters  and it would be easy for you to remember . Try gktoday or any online website . 

For LOGICAL REASONING   SSC papers which have got loads of good questions from this section , for analytical reasoning purchase MK Pandey's analytical reasoning ; Competitive reasoning by Pratiyogita Kiran; Modern Approach to logical reasoning by RS Sharma . 

APTITUTE RELATED TO FIELD OF MANAGEMENT AND COMMUNICATION SKILLS :  This section takes the least time to solve because questions asked are based on knowledge of basic communication skills and management aptitude
