laxmi u need to analysis whther u r good at theory or problems..after SWOT analysis if u think u can score higher marks in theory u can after reading the topic write mock test and compare the answers of that given in the suggested answers/module....improve presentation coz knowledge is not what u think u've but what exminer think u've....but don't ignore any subject....emphasis on concepts and not on magging....writing answers say in MICS in own words give better impression to examiner..hope this helps
