I wonder if my situation is common for training

Am doing my TC

But spending my weekends in office from 830 am to 1 am for saturday and sunday weekends

for weekdays the hours end at 2 am

there is too much work.

yet when I submit my work to bosses or associates, they are always not happy with my draft and throw it back at me for more amendments.
I kept getting scolded.
I am disheartened and wonder if law is really for me at all.
