Traveller needs advice

[Traveller]

I’m a newbie.
To complete my degree, I need to complete 6 exams. They all have to be upper level DSST.
I presently live and teach in a remote Canadian arctic community, and I will not be leaving here until the end of June. Because I will be leaving Canada in August for a year I want to complete my exams in the second week of July. I have to travel and stay overnight to do these exams. I also have other traveling to do for the remainder of July.
I have to fill a science requirement and chose Environment and Humanity Race to Save the Planet; I just have to do revisions on this now. Principles of Finance will be relatively easy because of my financial background.
I’ve explored Sparks Charts for these two and I think they would be a good resource to buy. I like that I can read them anytime.
Are there any more charts out there like the Sparks Charts?

Probably Human Resources Management- I have notes from Get College Credits. However I think that notes on Sparks Charts is more inline with the Instant Cert flash cards.
I need to come up with three more classes.

Money and Banking? I’ve worked in the Canadian banking system which is different to the U.S. I went through the flash cards and I won’t do this one.

I want to do the three others that are a bit integrated or relatively easy.

Advice and suggestions please.

Thanks,
Travie
