The test series and the mock interview were extremely beneficial, I only followed Byju's Exam Prep test series. Writing test series, I am a final semester post graduate student so I had limited time to prepare so watching video lectures would need lot of time, I wrote a large number of Byju's Exam Prep test series, the test series were extremely helpful, there was in depth analysis and all types of questions were covered, and also Byju's Exam Prep provided a through analysis of each test series so that you know where to improve, here the sectional test came to play, to strengthen your week areas and also detailed step by step solutions were also provided
