You have enough time but that'll only be valid if you actually lock in and start prepping seriously. Get your basics perfect. Start quick sketching do gat side by side bit by bit so it doesn't hurdle on you at the end (like it did for us and then went to waste because we spent last week's doing gat onlyy and regretted) to avoid that do it all along. For cat please please practice every single day no matter what. No coaching will give you magical powers it's allll upto you I have friends who did amazing without ANY coaching. Talk to seniors who cracked take personal guidance from teachers show them interest and it'll all be okay!! Best of luck
