Preparations for basic and A school

So I swore in like a week ago and ship out for bootcamp Sept 14th. I chose HM as my rate since I didn’t pass the color section of Meps and couldn’t get IT or IS because of it. I’m doing my best to get into shape for basic cause as of right now I’m in the big boy program. I can do the plank and pushups to satisfactory but my run time is horrendous. I’ve been doing boxing and running to crack the time down but should I be doing anything else to prepare?? Not just physically but also mentally or knowledge wise??
