Ongoing and future galaxy surveys, e.g., DESI, Euclid, WFIRST, etc., are going to collect >100M galaxy redshifts and reach sub-percentage precision on the cosmological measurements, e.g., Baryon Acoustic Oscillations, growth rates of large-scale structure, etc. We look forward to obtaining tighter constraints on the cosmological parameters, e.g., Hubble constant, equation of state of dark energy, etc. But meanwhile, we have to ask: are we ready to analyze such a massive data set? Are we sure that the systematics are under control? In this talk, I will report on what we have done and been doing towards this goal.
