Hi Nithya, the speed in the DILR section will come as you practice them more. Please solve good quality CAT level RCs regularly to get an idea of how a DILR set will be in actual CAT. You can start by solving at least 2 DILR cases per day from our site at https://www.mockat.com/prepzone/#practice. The cases were curated based on difficulty level, starting from level-1 to level-3. These will give you a good start to solving quality DILR sets and also record your time taken.
I am taking about 30 minutes to solve a DILR case and still may not solve a few of them, how do I improve my speed in DILR?
