My advice for u is that while going for examination always keep in mind it is quality what matters most & not the quantity. instead of trying to write everything just focus on what examiner wants.
In practical exams we all know what will be the format of giving the answers, so most of the students write what the examiner ask in questions. But in case of theory papers most of the student don't know the way to present their answers and they always ends up writing the excess information, which waste their lots of time and also does not fetch marks for them.
So what u need to do is after completing all of your syllabus must go through compilers issued by the ICAI. do them 2-3 times and I am sure it will help u in improving the presentation of your answers and you will get an idea about the length of answers and matter to b written in papers.
And most important thing i will suggest u to do is, discuss everything what u read with other students doing pcc with u. Make a group& try to study together, discuss case laws, questions and those points where you have doubts. Discussing will help in clearing your concepts and build your base in subject and most important thing is that the points discussed in the group will always remain in your head without any revision :P
so best of luck for your exams
I know it is tough but it doesnt mean that it is impossible :)
Stay positive don't panic don't let the fear control your mind :)
thats all from my side and rest is upon u :)
take care and best of luck for future
