Tougher batch less self study vs 2nd highest batch more time for self study

I'm going to sri chaitanya for 11,12 (not happy abt it but its the only school with good faculty near me ), the main thing I wanted to know was is the highest batch which goes from 7am-7pm better or the 2 ng highest batch (9-5).

the highest batch is more jee adv focused (at least that's what they said)

while the lower one is more jee main focused.

so my question is will the extra time spent in school be worth it or is it better so do self study at home, while doing the mock exams they give.

note-both batches give u mock exams for mains and adv (sat and sun, Sunday one is online) only difference is that there top batch focuses more on the adv level qs

thx in adv for any help
