Need Advice on Allen Online Dropper Batch

i'm currently in 12th (pcm+cs) and appearing for my board exams. i gave jee mains session 1 and scored 73%ile. i'm considering taking a drop and looking into allen's online dropper batch.

if anyone has experience with it, how good is the teaching quality, doubt-solving, and test series compared to offline coaching? also, how well does it prepare you for jee advanced?

would love to hear any recommendations or alternative suggestions as well. thanks!
