These two competitive examinations are considered vital and many candidates appear for both

It was confusion and clashes as postgraduates geared up for the competitive exam season. Yet, Mumbai University (MU) set them their biggest test. To be in two places at the same time!
A report in this paper stated how the varsity scheduled its PET (PhD Entrance Test) on December 16, on the same day the Council of Scientific and Industrial Research (CISR) has set its NET (National Eligibility Test). These two competitive examinations are considered vital and many candidates appear for both. The CSIR NET is only for Science postgraduates and has two exam centres in Maharashtra in Pune and Nagpur. Thousands appear for it. The PET is MU's entrance test to filter PhD applications. All postgraduates are eligible to appear for it.
