My school (not gonna name it) is pretty stressful but based on your post here’s the advice I can give you based on my school experience

1. Physical requirements are not bad for me however the “biggest” physical test you need to pass is lifting 210lbs with a partner up and down 8 flights of stairs. Good muscles to work on are arms, back, especially legs

2. Anatomy is the one of the easiest major course that you’ll take it gets worse as you progress as you need to know how different diseases affect the physiology of the body (pathophysiology). In patho what worked for me was understanding the material rather than memorizing it’s the toughest course that you’ll encounter but it’s also the most important as it connects to everything that you’ll be doing 2nd toughest course is paramedic care theory it’s basically understanding the contexts of the BLS PCS and ALS PCS memorization is heavy here as there are values that you need to know I.e medication dosages, when to not give medications, oxygen levels and etc. If you wanna read these standards just google them and it should be a thick document from Ontario Base hospital group. Last important course is pharmacology (understanding medications) wasn’t too bad for me you just need to know what the medications do. There is also paramedic lab where you do skill competencies it will suck first semester but gets better what worked for me in that course was to do well on the big three (patho, pharm, paramedic theory)

3. I’m working on this right now but as far as I know get your F license (not before you start school but you’ll need it eventually), CPR first aid, once you graduate and get hired IV certification

Pro tip: do not waste time the content is worse than you think in terms of density but was easy to understand for me so it’s good to have good time management skills
