Then if you go through all the sample papers given by ICAI on website I guess 3-4 papers are there for each subject. you can easily get B. however if you have your own good knowledge base you can achieve A too. I gave the test on 22 Dec 2018 for Lev 2. I secured A grade. More than 80% questions are from such sample papers.
do i need to go throught first level sample papers also or only second lebel sample paper and i dont have much practical knowledge since i am doing articleship in small firm
ok..first go for 2nd level papers. They are harder than 1st one. If you get time, then go for 1st level papers. However, in my test most of the questions were ditto same from 2nd year papers only.
