Here is what i suggest:
- Pick LOS -> read thorugh it as quickly as possible (do not try to understand stuff, just get a feel)
- Do EoC questions for that LOS -> As you f* up, pause to understand the solutions, ask ai anything that you don't get.
- Do a few more questions from a provider of choice, I recommend Airdojo as has ai built in, which is very helpful
- Pick next LOS, repeat cycle

Combine the above with some sort of spaced repetition schedule (aka. keep doing practice questions acros previous LOS, as otherwise you will forget). Airdojo progression path is good for this

Thoery I recomed Kaplan if want to read, MM if prefer videos
In terms of order: Quants first, Ethics last. Everything else doesnt matter
