HI,

I would like to divide CAT preparation in three broad areas:

Prepare for Basic Fundamentals

Improve with practice

Sharpen your test taking skills

As you have lot of time ,i would recommend not to lose interest and focus daily atleast two to three hours so that you can crack the exam and also try to concentrate and do all the section like english,quants, resoning on daily basis ,,dnt stick to one section as it may cause bordom

20% of your time – Reading books, novels, magazines, newspapers..

25% of your time – Basic fundamentals of Quantitative Aptitude. Be clear with all the necessary concepts and formulas. 

25% of your time – Basic fundamentals of Verbal Ability. Try and understand the concepts of grammar. Learn what Critical Reasoning is all about. Try to differentiate between statements, assumptions, conclusions, facts, inferences, judgments. These things can get really confusing at a later stage if your basics are not clear.

30% of your time – This time should be spent practicing some easy Logical Reasoning, Data interpretation, Reading Comprehension questions. This will help you understand what these sections are all about. It will also help you increase your comfort level with these areas.

You have many online sites ,you can refer for preparation too

GOOD LUCK
