We present the evolutionary scenarios for three eclipsing twin($q(M_2/M_1)\sim$1) binary systems using their combined spectroscopic andphotometric data. Using accurate \textit{TESS} photometric data, RVmeasurements, and spectroscopic data enabled us to calculate fundamentalparameters, such as mass and radius, better than 2 percent. The temperature ofeach component and metallicity of the systems have been obtained viahigh-resolution spectra. According to our spectral analysis, the metallicityvalues of AN Cam, RS Ari, and V455 Aur are \text{[M/H]}=\,0.00$\pm$0.12,0.05$\pm$0.08, and -0.07$\pm$0.07, respectively. Using the derived metallicityfor each system, initial orbital parameters and detailed evolutionary status ofthese three systems are calculated with high precision by using \textsc{mesa}.According to our analysis, both components of AN Cam have passed the terminalage main-sequence, the primary component of RS Ari is in the giant phase whilethe secondary component has passed the terminal age main-sequence, finally,both components of V455 Aur are still on the main-sequence. The current ages ofthe three systems AN Cam, RS Ari, and V455 Aur are 3.0, 3.3, and 1.4 Gyrs,respectively, and they will approximately start to transfer mass betweencomponents in 400, 250, and 2700 Myrs, respectively.
