which DILR topic is important for CAT .

Hi, in my experience so far, DILR is pretty volatile in CAT. With the passing years, the difficulty level of the section is only going upwards. After various sessions the only conclusion that I've come to, personally, is that you cannot really focus on a particular topic and expect yourself to do well on the D-day. All the questions are generally an amalgamation of at least 2-3 concepts. So my suggestion would be for you to be consistent with your practice, attempt at least 2-5 sets on a daily basis with varying difficulty.

Focus on: Games and Tournament Venn Diagram Arrangements Routes and Network Table with missing values. Best of Luck.
