Redo unscored and scored OR review them instead?

So I finish my 2nd run on SB. For the unscored and scored, I'm redoing the unscored rn and just feels like it doesn't help since I pretty much rmb the answer -_-. Should I just review them instead of re-doing them? What do you guys think? (I'll prob redo only the CARS tho, since it's my weakest and just want to get the logic right =,=")
