4. Why are previous year papers important?
Previous year papers are essential to follow in any kind of examination since it gives a holistic idea on which part to focus more. Solving these papers will make candidates aware of their weaker areas and they can pay more attention to the same. Solved papers also prove beneficial as the solutions are compiled by research scholars and thus are authentically made solely for students' benefit. Candidates should make a fixed routine and adhere to it while solving these papers. This will allow them to practice all the chapters with equal importance.
5. Where can we find the previous year papers?
Last year IOAA papers are made available on the Vedantu platform and candidates can download them for free. Once downloaded they can be accessed in offline mode as well. Buying hard copies of the previous year papers can be really expensive. Thus by making it available on this platform, absolutely free of cost, Vedantu has tried to make the learning process easier for candidates, which proves to be cost-effective as well as interesting. Once done with the chapters, candidates are advised to solve these papers regularly.
6. Why should we refer to Vedantu?
Candidates are advised to visit this platform for essential details and updates regarding the examination. Vedantu makes it easier for candidates to get all the reference materials and question papers handy for candidates so that they do not feel lost amidst all the burdens that they have to take. They make sure that candidates find interest and can delve deeper into the contents of the subjects, clarify their doubts and take an active part in the mock-tests conducted weekly by experts on this platform itself.
