The release of TESS light-curves gives us the opportunity to perform all-sky seismology for a lot of stars. Among them, the higher quality data that was obtained from the longer light-curves of the South Continuous Viewing Zone (SCVZ) correspond to the best opportunity to conduct precise seismology. In this work we present the first attempt to measure precisely the evolutionary status of a large number red giants stars with TESS data in order to assess the potentiality of those data to perform precise seimsology.
