Hi there!
I didn't do Power ('Reason' was my Foundation subject) but most of my other Arts friends did, so unless someone else with more experience jumps in, I'm happy to help.
Re: understanding lectures, trust me, I know what it's like to get frustrated with academics who babble on with their verbose jargon to seem important. It's even worse when you
do understand what they're saying and you realise it's often totally meaningless

A couple of things I'd recommend:
- if you're attending lectures, keep a running tally of the words/phrases you don't understand, and look them up yourself later
- just focus on the general gist of what's being said in the lecture, then go home, watch the recording, and 'translate' the academic lingo
- talk to your tutor about any unfamiliar concepts - you can even bring this up as a tute discussion point if possible. Just say 'hey, I was wondering if we could talk about this whole 'hegemony' thing since I didn't really get it on Wednesday - any ideas?'
Re: readings... I'm tempted to tell you to just skip the ones you don't get since it's not crucial to understand all of them, but if you're not understanding >50% of them, then it's worth breaking them down. Same process as above - isolate the bits you can't grasp and either look them up, or ask your tutor. If there are PASS classes for Power, they might be worth sussing out too since you'll be able to ask a high scoring student from the 2015 cohort about some of this stuff.
Re: assessment: if it's like Reason, I believe you'll have an 'annotated bibliography' as your first task, and then two essays later in the semester? Or is it one essay and one 'take home exam' (which is basically just an essay in a shorter time span)? You'll likely get a choice of a bunch of topics that will allow you to just focus on the bits of the course you understood and found most interessting. From memory, Reason had the bibliography thing (~10%), then one major essay (~50%) on the broadest possible prompt (eg. 'Reason is kinda complicated. Discuss.') followed by the take home exam (~40%) where we got 48 hours to respond to one of three prompts... or something like that.
I'd definitely talk to your tutor about assessments though, since their primary role in Foundation subjects is to help you understand how that whole process works.
Let me know if that doesn't make sense - sorry I can't offer more specific advice; there aren't many Arts-ish people on the forums
