Dear friend,
To have the perfect studies it is advisable to have our own notes. This is because, while revising at last minute we will surely recall all the details that we studied at the time of making the same notes. One short way, as u said is to refer to other's notes, but remember they will remail only a guiding path, unless and until ur brain absorbs it deeply u will not be benefited in the exam. So, it is much better to have ur own notes. The time consideration u have said is not so enough, there is equal time for all of us, for ranker and a failuer. dont run for just covering the syllabus, but cover it with proper unsderstanding. I am telling u with my porsonal experience, if we just complete our entire syllabus fastly, we think that we know all the things but the case is not so. At the time of writing exam we will come to know that whatever we have done fastly was just a going through. so it requires a deep study. Remember CA exams are not easy. U have to study completely. Utilise ur time effectively. and go subject wise, prepare it as if the exam is tommorrow. Stay calm and quite. dont think of other subjects while doing one subject. just think that u have to show ur best only in current subject, apply this crietaria for all the subjects. So please avoid running for completing the subject without understanding it. lastely, prepare ur own notes for each and every subject. Best of luck. study hard hard and hard. thanks, regards, kARAN JOSHI.
