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