excluding js/jquery/jquery.js works but it kills my pagespeed score.
I’m afraid this is a cake-dilemma (having or eating it); a lot of themes/ plugins require jquery being loaded early and apparently so does your slider. this means that you will either have to exclude jquery from optimization or that you’ll have to consider switching sliders to one that does not require jquery being excluded from optimization (I saw someone mention “css slider”) or ditch the slider, but that may be a bit drastic.
hope this helps,
