I am a physicist working in TCS in a new group. I would like to know, given a conference (imagine your favorite ones), how can I know the quality of this conference and also the quality of the journal where the proceedings will be pusblished (in case they are). I heard something about CORE classification but found no link or more information about. Thanks
P.S.: I find TCS stack exchange very interesting for TCS discussions (obviously). I just wonder if there is any similar stack exchange academic site for physics/chemistry. I found physics.stackexchange, but some questions related with journals were instantly classified as offtopic
