Using Wood's (1972) model the lightcurves of six eclipsing binaries (V523 Cas, GT Cep, RV Crv, RU Eri, UV Psc, and V499 Sco) whose general properties have not yet been discussed adequately have been reanalyzed. For all binaries (except UV Psc) photometric elements appreciably different from those previously deduced from the same observational material have been derived, while a more consistent interpretation of the binaries studied has been achieved. The W UMa-type binary V523 Cas appears to be a contract system of the W-type subclass. GT Cep is found to be a normal semidetached system. RV Crv is very likely to be an evolved contact binary, whereas RU Eri may also be related to the contact systems. The early-type binary V499 Sco and the RS CVn binary UV Psc turn out to be detached systems with main-sequence components.
