hey there , don ' t put so much pressure on yourself just because you come from an elite school ! ! i was from one of the top secondary schools and i was so devastated by my o lvl results because it wasn ' t up to the school ' s standards . i realised that it ' s more important to live up to your own expectations and not any other people . i ' m also not the studious type , like i only do 12 practices for each subject but to me i think it ' s enough . just do whatever you can to the best of your ability , ignore how much others are doing . and i think it ' s really admirable to see you encouraging others all the time . all the best for phy p 1 ! ! <| sep |> check your extruder lever arm to see if it is putting enough pressure on the filament to feed it properly .
