Dear Gourav,
Your subject to cover during this period of (10th October to31st October)-21days
1. Information technology:- which is the simple and needs more reading. you can allot 20% of time for this subject. if you cover flow chart and decision table, you are guaranteed with 15 marks. and cover word, excel & power point to get another 15 marks. telecommunication and internet fetch you 20 marks and data base for another 10 marks. concentrate more on this.
2. Income tax and cst:- cst is the simplest of all in second group. its complete coverage takes not more than 1 day, you will get 25 marks question. In income tax you have to practise regularly the problems from all chapter, so that you could get another 40 marks. check for latest amendments from RTP, which will regularly asking for objective questions aroung 20 marks.
3. Costing and FM:- normally 30-40 marks are theory questions, which you could easily cover. in addition FM you have to cover only capital budgeting, working capital management, ratio analysis chapter to get more marks. and in costing you have to cover problems from material, labor,overhead and process costing to get more marks.
the plan I given is to concentrate more on the scoring area. As it is professional examination, if time permits you have to cover other chapters too.
All the best
