hi,

see as per the syllabus of karnataka pgcet mca there is five units

1.  Mathematics

2. Computer Awareness Computer

3.  Analytical Ability and Logical Reasoning

4. General Awareness

5. general english

now the general ability parts covers Logical Reasoning, Quantitative reasoning and Visuo-spatial reasoning. however since the pattern is mcq type the suggestion making is quite difficult. I suggest you to follow the previous years papers and reasoning and quantitative books of rs aggarwal.
