Signals and systems

Hi, so in signals and systems (first year ece) i got 47 overall. (passed fat) Lot of people have told the overall pass critieria will definitely drop below 50. But i wanted to ask some seniors how exactly this works. for context, my class has done shit in sns consistently cat 1 avg- 27 cat 2 avg-28 quiz 1 avg- 6 quiz 2 avg -5 fat avg is probably 50. i am below the average and overall below 50. will the pass critiria decrease or will i fail ?
