Any advice on closing the gap from timed sections to PTs?

On timed sections, I'm regularly score between -1 & -3. However, when I take a PT, I totally bomb and score -6/7. What gives?! And how can I get my PT sections to look more like my timed practice?

Is there anyway to "mute" some of my older PTs so I can see a more updated list of my priorities? I don't necessarily want to delete the older ones - I just want to see my weak areas now vs. then
