Popis:	First orbital solution and photometric study for the newly discovered systems V968 CEP, ET CMI, and ES CMI was carried out by means of WD code (windows interface version) based on model atmosphere provided by Kurucz. Our modelling revealed absolute and physical parameters, which show that the primary components in all systems are hotter and more massive than the secondary components. According to the estimated parameters, the evolutionary statuses for all systems were estimated on theoretical mass-luminosity and mass-radius curves. Spectral types of the systems components were adopted using the estimated temperatures.
