I am joining the Marines,could somebody whose recently been thru it what should I really expect from bootcamp?

I Dep'ed in July 1st im confused with the way the jobs are chose. I don't have an mos yet but im supposed to leave August 10. I pes the IST but im still not sure if 1 month is enough time to get myself physically ready for boot camp. I started started running and doing push ups this week...3 days after i found out my leave date...my recruiter says i might leave in October instead of August because the job choices aren't that good right now. I would like to leave as soon as possible but I guess I could wait if the jobs will be better in October.For those of you who have been through it could you give me some advise please. Thanks
