Ca final nov`14

Hi guys I am a average student that's Wat my mark says but I know my capacity and I also know that I was lazy these many days I cleared ipcc by self preparation just 1.5 months I studied for that. Now it's time for ca final and I have hardly studied anything nor attended class just a week back I got leave from office. I feel this is the rite time to use all my saved energy and turn the show on I have a question to all my dear friends here is it possible to get a rank in ca final by studying for just 3 months??? Awaiting for your replies please be honest. If you guys say yes it's possible thank you so much it's a confidence boost but if you say it's not possible ha ha ha I would love to challenge that and make history :) Awaiting for your response.
