Disclaimer: Not a grad entrant, not sure how these work, but I just noticed something...Totally agree! Im in 3rd year too but extended my degree to 4 years so I can fit in more 200 + 300 level papersAll the best!
When you say extended your degree to 4 years, are you doing an Honours year?
There's a clause in the requirements for the Graduate category that says completed the requirements of a first degree "normally in the minimum academic time" - and that just makes me question whether you are still eligible if you do a 4-year degree with 200 & 300 level papers only. i.e. whether you'll need to do an Honours year with 400-level papers to be still eliglble. I don't want to cause alarm, but if your 4th year is not a 400-level Honours year I would urge you to check with the Health Sciences Admissions Office on whether this would still be accepted for graduate entry, just in case.
Also if you are in 3rd year right now, and are applying this year (2019), you will be scored under the old system (points-weighted GPA for each year, then weighted by year - with the exception that 100-level papers in 3rd year will not count.)
