Our study focuses on eclipsing Algol binary systems. We have performed photometric studies and analyses for three eclipsing Algol binary stars. Orbital and physical parameters of the recently discovered Algol type eclipsing binary systems GSC 04328-02164 and GSC 03164-01558 are determined. The spectral types of the primary and secondary components are F2 and G0 for the first system and G2 and K2 for the second system, the stars of the two systems are main sequence stars. The results have already been published in The Astronomical Journal, 151:19, 2016. Light curve models of QS Vir Algol system are constructed according to photometric observation using Kottamia telescope. Orbital and physical parameters are determined. The primary white dwarf is more massive and hotter than the secondary red dwarf component. O−C curve studies indicate that the change in the orbital period P• =1.108*10^-8 d yr^-1 and the mass-loss rate M• = 2.348*10^-8 M⊙ y^-1
