PHS is a drain, half the time im sitting there not soaking up any info given (i really dont know what to understand in that unit), there's really no active learning for the unit (at least for lectures anyway)
There's a lot to memorise in that one, due to a wide range of topics they throw at you (and you wouldn't have come across them in high school). PHS II is much better if that gives you some future confidence - most of it is an introduction to psychology and it's structured in a way you'd be able to pick topics out and study them.
Do your "Medicines in Profile" and learn them. [Wait, do you have that still? ... I could actually give you mine if you need]. Know your basic latin short hand. Louis Roller's lecture notes are the worst (even though he's awesome), don't even bother studying from them - go get a textbook. I think you have simple calculations you have to learn. Know your labels, your prescriptions and how to read them/error spotting... Can't remember if you need to remember ancillary labels... I think they also introduce you to the professional ethics stuff, and pharmacy organisations. There was also the poisons' schedule (S2, S3, S8... etc) and you should know which are which; e.g. S3 is 'pharmacist only medicines' and you don't need a script but they can only be supplied by a pharmacy (e.g. Panadeine - paracetamol with codeine), S8 are controlled drugs such as Endone (generic name oxycodone) and they need to be carefully dispensed so that they're not abused (in a real life pharmacy you have to write them off in a special book). There should be overviews, learning objectives or aims near the start of each lecture. Consider going through those.
... and yeah I agree, most lectures are boring lol. Depends who you get really. D. Malone, Safeera, Mallanack ... they're some of the good ones.
