In the study, we present the results of new transit observations of two hot Jupiter WASP-10 b and WASP-11 b using the T100 telescope in Turkey. By analyzing the new transit light curves with the MCMC method through EXOFASTv2, we updated the physical parameters of two hot-Jupiter systems. The updated parameters are in agreement with the previously determined values within the uncertainties except eccentricity and impact factor. Starspot activity, noticed in previous studies, was not clearly detectable due to our highly scattering transit light curves of both systems. We determined an updated linear ephemeris and orbital period for the two systems by combining our new mid-transit times with the ones in the literature. There is no significant evidence for the orbital period variation of the systems in the most-updated O - C diagram. In addition, we could not find any strong signals for both two systems in the period analysis.
