If your heart is set on the PN program now, you should just focus and do the best you can before thinking of other options.
There is other options that you could take if you do not qualify or accepted in a bridging program. Athabasca has to online LPN to RN program that only requires 1 full year of PN work hours before starting.
As for work, I wouldn't say it's difficult if you're in flex, but at times, I do want to just stay home and study, and I could've done way better than what the title of this thread is suggesting. I'm not too sure of your background, I work as a Pharmacy Technician for couple of years now, and although I did not find some of the stuff as difficult as other people (Patho and Theory in particular), it is still quite intense compared to other college programs.
You should aim for (at least) an A in: Psychology, PPG1, PPG2; B in Anatomy, English, Patho, Health Assessment; C+ in Theory. This is a realistic mark you should aim for if you're planning to bridge IMO.
I do have peers who's an international student, who would read every chance they get, and still ends up failing or barely passing patho and/or theory. Young adult who think they could breeze through it who failed, and people who studies way more than I do, but still find themselves around the pass/fail territory still.
I guess I threw in a little bit more than you're expecting, but what I'm trying to say is if you're planning to bridge, depending on your study habits, depending on your knowledge base, you should really weigh how much 'work' you can fit into your schedule without sacrificing marks here and there that could jeopardize your chance.
