you should be clear with the concepts.. present things well give a note wherever required make sure you present working notes when required ... write the sections only when you know it is 100% correct or else its better not to mention any section... Tax rates , deductions , etc remember them well amd use them wisely thank you ALL the best
Firstly quote more & more sections. Secondly give working notes as each note fetch you extra marks.... Thirdly give all answers with conceptual clarity.
