Just to add that the guide is the 2nd post. The one you linked points to the main one where it’s mostly about me rambling about my Japanese journey and reaching level 60 
This is the link for the actual guide:
@skeletonjoe, don’t worry too much about not getting everything correct. We’re here to learn, not ace tests. We shouldn’t expect ourselves to know it all and get 100% accuracy precisely because we’re going through a learning process 
A good tip to improve accuracy that hasn’t been mentioned yet is to just give more time to yourself when you’re doing lessons. Read the mnemonics, check the example sentences, say the meanings and readings to yourself or out loud without checking for the answers, etc
