I am not confident with LRDI section , could anyone suggest me hard LRDI section of maybe last year or any of the Dashcat mock provided my crack u to take?

Hi
Try to attempt all the 15 LRDI sectionals. They are of different difficulty levels. You can choose either not to see the difficulty level of the sectionals in order to give them without any preconceived notion or to take an easy/difficult sectional to fine-tune your preparation. We have enabled this feature for our students. Do not be mistaken to assume that the difficult sectionals have difficult questions/sets only and vice versa. A difficult sectional will have a higher proportion of moderate-difficult questions than an easy sectional.
In addition you can appear for all past year CAT papers as sectionals to boost your confidence in this section.
