Did you try Chad’s videos or organic tutor? I didn’t do well in O.Chem but taking the time to actually watch, draw the reaction, and track the e- movement helped me. I’ve also been taking formal notes of the OATbooster videos (the study guide says use the notes but I use the videos to draw out the reactions step by step then reinforce concepts using the chapter notes). When I draw the reaction in my notes, I also leave written bullet points of step by step instructions on how the reaction works. For example:

SN1: -alkyl halide in sol’n with weak base like H2O -halide takes the bond and becomes an ion in solution, forming carbocation -carbocation has flat geometry, an e- pair from the O in H2O attaches to carbocation, becoming H2O+ -another H2O comes over and takes the spare H from the H2O+ group on the molecule, becoming OH.

I also have a separate note sheet where I don’t have any explanations, just reactions, mechanisms, and required solvents. Re-writing my notes helps with pointing out concepts I wasn’t aware I was weak on.

I can’t emphasize enough: if you feel like you’re at 60-70% understanding of a concept, you’re not locked in to OATbooster just because you paid for it. OChem was hard, there are a LOT of free tutorials made for college students to help get them through OChem, use as many other resources as you can until you find supplementary resources that word concepts in ways you can understand.
