Where to get a fourth UL History course?

[Pelican]

TESU finished evaluating my transcripts, and I found I'm further from completing a BA in History than I previously estimated. I need four UL History courses. I already am in-progress on the UL Civil War and UL Vietnam War courses at Study.com. I also plan to take the DSST in Soviet History, which I believe is also UL. But that leaves me one course away. Does anyone know an affordable source of one additional course? If I took an UL Historical Methods, can that could to fulfill both the UL History and Historical Methods requirement, appearing in both places on the credit evaluation?
