650-680 SAT Chem Barrons

I just took my first SAT Chem test from Barron’s. I haven’t covered Organic Chem, Acid base, Oxidation Reduction, and The Lab along with some Representative families and groups. I pretty much missed every single question from these chapters. With that in mind, is my score ok for now? I’m trying to get ready for the May 2 SAT. Should I postpone? Or will studying for 41 days be enough?

Yeah I pretty much found a lot of silly mistakes, so the May 2 is a go.
