I'm hoping to get a 170 on the June test (6/6/24). Usually I do the best with logic games (-1/-0). Lately, I'm feeling like I'm regressing as I get closer to my test date. Any tips? Ways to stay motivated?

Here's a breakdown of my PTs (I've been taking 2-3 a week for the past few weeks, but my earliest one was 6 months ago):

PT66 - 149 (earliest)

PT68 - 149

PT20 - 159

PT47 - 165

PTJ07 -163

PT72 - 163

PT76 - 167

PT77 - 162

PT79 - 167

PT80 - 171 (when I started doing 2-3 a week)

PT81 - 166

PT82 - 168

PT83 - 177

PT84 - 168

PT85 - 169

PT86 - 166

PT87 - 167

PT88 - 166 (today)

Any help/advice/motivation would be appreciated :)
