Hi Prakash.. Please do not fear ans definitely do not skip the attempt due to this fear. No matter how much time is left.. Just start preparing from today.. and try to cover Costing first as it is very scoring and do IDT as it is not that lenghty like DT.
I would also suggest you to join any test series.. because it will help you in the exam. Also, in case u need more conceptual clarity or need to take class for any subject, u can go for any FAST TRACK pen drive classes. You can visit conferenza website for that in case u need it..
you have plenty time in your hands so its sufficient. As mentioned by others, if you need conceptual clarity you can purchase fasttrack lectures from conferenza.in
As MCQs are playing an important part in exams you have to focus on them too. There is an app called conferenza MCQs app which is available free of cost in play store. it has 1000s of MCQs in each and every subject divided chapter wise. all the concepts are covered head to toe. Do refer those MCQs from the beginning itself
