Multi-colour WBVR photoelectric observations of the eclipsing binaries IT Cas, CO Cep, and Al Hya were carried out. The photometric elements and the absolute parameters of the orbits and components were obtained. The valuation of the angular rate of the apsidal motion of Al Hya based on the comparison of our observations with the previous photoelectric light curve of this system was derived
