Grammar is tested either through sentence correction, error identification or fill in the blanks.
Reading Comprehension: Typically there are around 5 to 6 passages followed with 5 to 6questions per passage. Each of the passages would be of around 800 to 1300 words. The questions are a good mix of fact based and inference based.
RC passages are long and often based on unfamiliar topics. The basic idea is to test your speed and comprehension skills.
Problem Solving CAT problem solving questions are designed more to test your understanding of underlying mathematical concepts than to test your ability to actually carry out quantitative procedures accurately. Fortunately for many test takers, advanced quantitative topics, such as trigonometry and calculus, are not tested on the CAT. To score well, you only need to be familiar with basic arithmetic, geometry, and algebra, as taught at the high school level. Any decent CAT prep book will cover these quantitative concepts.

DI-DS-LR Section has 3 parts
Data Interpretation tests how well one can interpret information from raw data given. Second skill tested is if one can do calculations without the help of a calculator and that too fast enough.
CAT test writers use data sufficiency questions to test your ability to "reason quantitatively." This stands in sharp contrast to the problem solving section, which is designed to test how well you manipulate numbers. If you find yourself doing a lot of number crunching on the data sufficiency questions, you are doing something wrong.
You can think of critical reasoning questions as, essentially, mini reading comprehension questions. These questions tend to follow passages that are one paragraph in length. These questions primarily test the analytical and critical thinking skills that admissions committees so badly want to see in their applicants.
