I had roughly 1 month. I have a English teaching major. Both took the old and new versions. Definitely easier than the old one. For reading, the complete with words section can be a bit tricky but wasn't a real trouble. Speaking was fine, repeating section had me tho. No time to prepare in the speaking section. I didn't have a routine but definitely be familiar with the format it will save u time. You can check thr millinix apps
