I guess what gets me is the inference questions because I always end up choosing the second best answer

Ah! Well, then, I suppose I am going to provide some advice that will not be particularly surprising and that you have probably already thought of yourself: drill inference questions. Read the answers to understand the explanation.
Do the set
score it
read the answers
REDO the passage with the answers in front of you
then put the section away
come back later and retake the section, applying the explanations you read
Take another break
Try a new section
etc.
I wish I had a silver bullet for you...
