>Only the top tiers are strong surely
Even regular students are shown casually lifting a couple hundred lbs to a half ton occasionally. To see normal students doing super human things casually is common

The only school where students seem almost human tier weak is Millennium, but even then volume F kinda hints they might be faking it in front of sensei. Yuuka claimed she has weaker stamina than sensei only for her to be running on top of falling rubble to fight Hod in a collapsing city. Chances are she was lying about being weak.
