Coaching for CFA L1

I have registered for CFA L1 attempt (feb 2027). Initially I thought, I could do it w/o coaching. Since most of the people I have taken advice from said that at the end - They prepared through CFAI material and dropped the lectures.

But now w/o coaching, I feel very unstructured. I have already wasted 10 days on this. I am confused about prep providers. Should I go for Parth Verma? Any experience?

Or will Let me explain work? Will I need additional resources with these two?
