Sparkly- Maybe you bit off more than you can chew. If you are taking very difficult classes, then take fewer credits that semester, or balance them with easier ones. Maybe you need a vacation-next year consider taking one instead of summer session. even if it takes a bit longer to graduate, it will be worth it if it keeps you from burning out.
Just wondering- you are very set in being a pharmacist. Why did you decide that if you were not successful in science before?
Syag, is it the degree you specifically need, or the learning/training such courses would give you? There are many free online courses out there, some you only pay if you want the certificate at the end. There are also many online MSc programs, study at your own pace. Online learning is very competitive nowadays, so with enough research, you may find an affordable program. I am not sure that you can get government student aid at the graduate level, but some programs have fellowships, work and learn options. I see education switching directions in the near future in terms of the job market- with so many online options that are cheaper than brick and mortar universities, it will be less critical where you got your degree, and more important to a potential employer that you have acquired the right skills and more practical knowledge. It’s also great for the frum community, because they can get degrees without being exposed to the campus environment- whether it is pritzus, liberal brainwashing or the ever-growing anti-semitism.
