If you apply for Study.com's Guardian Scholarship, you'll have to take Personal Finance (for 3cr Free Electives) and then you have 5 more classes free. For Info Lit, you could use their Intro To World Religion or Advanced Tech Writing. Religion just has 90ish 5 question multiple choice quizzes (top score out of 3 attempts counts, so you can get pretty close to 100% on all of these, which means you only need 55% on the final!), plus the 100 question, multiple choice final. Tech writing is more quizzes (120 maybe?) a 500-800 word project, and a 100-question multiple choice final. They also offer American Government...100ish quizzes plus the final. If you read quickly, you can skim through the lessons on both to knock out quizzes quickly. Plus you can test at any time of day, no scheduling in advance. So this format may be a good fit for you. (They're a bit mindnumbing, but just keep hammering them out.) If you did Religion or TechWrite, and then Gov't, you'd still have 3 more free classes available, if you need electives.
For phys/chem - Do you need labs? Do you feel confident learning these independently? Straighterline offers Physics 1 and Chem 1, both with labs. Saylor Academy offers all 3, but only the classroom side - if you need labs, you'll have to take that separately. TESU does offer the labs separately, so you could do Saylor's independent study and then TESU for labs...TESU lab-only classes are 6 weeks, I believe, instead of 12. Excelsior offers 15 week class/lab combos, but the standalone labs are only 8 weeks. American Public University offers them all but check the schedule to see what months they're starting - they're all 15 or 16 weeks, I think. University of North Dakota is offering a 2 month summer chemistry with lab online, but it's Intro Chem, which may not be enough for the requirement...will intro do, or do they want General Chem? SUNY Empire State has Physics 2 with lab.
Honestly, the most straightforward way to do these would be to hit your local community college - cheap classes, lab equipment provided by college, and instructors available in case you get stuck. They'll be registering for summer term right now.
If you want to apply for graduation in December (deadline to apply is 1OCT), you're tight on time for the sciences. One of the more knowledgeable posters can help on this...but I think if you want the December graduation, you'll need all your coursework done by the end of October? So a fall community college class probably wouldn't work, just the summer ones.
ETA - Saylor does have the physics, it's just that they call Phys 1 "Mechanics" and Phys 2 "Electromagnetics". Also, do you know if you need calculus-based physics, or will algebra-based be enough? That kinda throws a wrench in it, if you have to have calc based. APU offers it, ASU offers it. 4-yr colleges offer it, typically. A community college with an Engineering/Science transfer option probably offers it.
