We present photometric observations of three variable stars carried out as a part of the observationalpractice included in the undergraduated course Physical Methods of the Observation at the University of San Juan, Argentina. The observations were made using the Double Astrograph Telescope of the Carlos Ulrico Cesco Astronomical Station belonging to the Fel ́ıx Aguilar Astronomical Observatory of the University of San Juan. We observed the variable stars V922 Sco, KZ Hya, and ASAS J102322-3737.0 with the aim of improving their periods and analyzing the instrument performance for low-amplitude variables. We obtained light curves with an accuracy of about 5 mmag and determined basic characteristics of the CCD cameras employed.
