Berkeley review vs Kaplan for nontrad

Which set would be best for a nontrad with a weak science background? I have 6 months to study, but wouldn’t mind taking it much earlier if possible. Leaning towards TBR, but I’m worried it will be too much for me based on the stuff I've read on here. If I do go the TBR route, plan to get the AAMC materials for sure, but would Uplanet be necessary?
