Abstract: We present the optical analysis of a sample of quasars selected for their significant variation in optical emission. Photometric analysis was carried for 22 sources and it was found that the colour change for the majority of the sample follows a typical behavior of Changing Look Quasars (CLQs) as suggested in the literature. Spectroscopic analysis was carried out on 2 sources to identify the origin of the observed variation.
