We present new photometric and spectroscopic observations and analyses forthe eclipsing binary systems V1241 Tau and GQ Dra. Our photometric light andradial velocity curves analyses combining with the TESS light curves show thatboth are conventional semi-detached binary systems. Their absolute parametersare also derived. We present the $O-C$ analyses of the systems and we proposethe most possible orbital period modulating mechanisms. Furthermore, Fourieranalyses are applied to the photometric residual data of the systems to checkfor the pulsational behavior of the components. We conclude that the primarycomponent of the system GQ Dra is a $\delta$ Sct type pulsator with a dominantpulsation frequency of 18.58 d$^{-1}$ based on our $B$ filter residual lightcurve although it can not be justified by 30-minute cadence TESS data. Nosatisfactory evidence of pulsational behaviour for V1241 Tau was verified.Finally, the evolutionary tracks of the components of both systems arecalculated, while their locations within evolutionary diagrams are comparedwith other Algol-type systems.
