don't worry heena ti happens sometimes......according to me u should dedicate most of ur time to cost as it seems ur weak point.....make ur practical portion strong don't depend on theory for this........then revise ur tax knowledge as u score good marks in it in last attempt it helps u attain the aggregate %.then learn IT SM as much  as u become confident in mind that u can easily score 45 -50 marks in it ..do selective study in IT SM its enough

give time to scanner & compiler to know about the important ones &repeated ones...

don't b tensed or panic just relax & do ur routine study
