CAT 2026 prep talks , more like seeking advice

Hey guys! It's my first ever post on reddit so please overlook any mistake/s (if any) made by me in this post.

SO coming back to the topic , I gave CAT 2025 (Slot 1) and managed to score only 51%ile in spite of months of preparation just because I didn't prepare seriously. I played a heavy price for my laziness and lack of discipline which cost me a whole year . I am preparing for CAT 2026 and OMETS . I was so cooked in CAT 2025 that I only managed to do 10 questions in the whole CAT SLOT 1 paper (8 in varc 1 in LRDI and 1 in QUANTS).

I have 2 main concerns . first how do I maintain discipline? And secondly, a guy so weak in LRDI. and Quants , if I start now , can I go from scoring 51%ile to a 99+%ile?? Is it possible? Please help me . Feel free to post your opinions !
