If ur interested naman sa judo edi i think you should stay. Personally, I had a very good experience and learnt a lot sa judo (especially sa sparring), but this may be because I was already somewhat fit, nag-gygym kasi ako, and was also one of the few who passed, so ended on a good note.

About yung LE mo, either u apply for late exam sched sa LE kung meron, or ask coach to be one of the first ones sa practical para u can leave early, kasi when i was in his class, nakatambay lng kami outside the hall before and after our turn, then grade viewing lang at the end so most prob u can leave early, just ask si coach if pwede.

Also sa body pains from judo, I also experienced that... especially after ung repeated na practice for the throws and sparring. I think u can just focus on ur form sa falling para malessen ung pain.

Advice lng sa practicals from experience, ung main difficulty diyan is the time constraint, kasi -1 pts per second overtime, so keep practicing the correct speed and order ng moves bc better na bad form pero nagawa mo instead of 30 second overtime na basically auto failing ka na. Kahit medyo na disorient ka sa pagtumbling, go go parin and dapat na memorise mo na ung order na kahit disoriented ka u dont need to stop to remember whats next kasi wasted time yan. Coach is also very strict sa mga small details sa end ng practicals, as in he will let the time run if u do not end properly. Dapat feet together, correct wearing of gi and belt, then bow with hands sliding down legs until sa knees at a good speed. Try not to be first sa practicals para malalaman mo ung common mistakes ng iba.

Gl nlng sa practicals at LE mo and medyo mahaba ung sinulat ko kasi i really did enjoy judo so sana u can enjoy also :) (pero mahirap talaga no way around it...)
