I've done the Pre-Health Sciences Program a while back at Fanshawe, in London. This was before they decided to make it into two different programs (i.e pathway to advanced diplomas vs. diploma's). I primarily decided to take it so that I could upgrade my High school marks and overall average, and have post-secondary credits, making it a bit easier to get into Nursing Programs. Have you ever taken any general science courses before? Chemistry? Biology? Physics? Math? If so, a lot of the material will be review and most likely have been taught to you before. However, and from what I can remember, the workload can get VERY HEAVY. Everything will seem to be consecutive in terms of exams and tests. It may be challenging but it shouldn't be hard, nor should you be struggling.
My best advice for you would be
1) Learn your study habits and what works best for you.
2) Become VERY organized. Use an Agenda, calendar and make DAILY to do lists for studying. Be Productive, and be an active learner.
3) Stay on top of ALL your readings and homework. They pile up fast.
4) If you don't understand a concept, do not wait for "Later". Email your teacher, Ask your friends, watch youtube videos and do what you can to understand it to the best of your abilities. If something is really not making any sense whatsoever, make an appointment with your teacher. They can easily figure out what you may be missing.
5) Make a GOOD group of friends who you can study well with. The closest friends I've made in my whole life, were my friends from Pre-health. (We used to call it Pre-hell haha and they've all gotten into their Nursing Programs/ Health Care Programs/ Degree programs of their choice)
6) Always find some time to Make time for yourself, but do not slack off. This is not a Program to slack off in (and Neither will nursing be lol)
Best of luck! If you have any more questions, don't be afraid to ask!
