I'm not confident to solve even 1 DILR question, What should I do?

Hi Ayush
Confidence builds with practice, as we have only a month left so you have to work hard and plan more strategically . Try to identify potential topics or topics from where questions have been repeatedly asked and can be asked this time as well for example arrangements, puzzles and venn diagrams . Try to go through the basics of these in a day or 2 and appear for topic tests of these as quickly as you can , Try not to worry and do not think before solving that you cannot solve or just by looking at once concluding that you won't be able to solve , try to read and extract information as much as you can and approach the set . Try to devote at least a week from now to only LRDI , watch You tube videos of Sayali Mam and Maruti sir , watch the two stream sessions of LRDI in live booster class and keep practicing.
All The Best !
