This goes to show that junior colleges are not necessarily superior to polytechnics nowadays. There is a greater acceptance that polytechnic is also a viable path for top students as well. I have numerous thoughts on polytechnic vs junior college debate, but they are too long to put in 1 post. End of the day, I think it comes down to learning style. Junior college is essentially secondary school on steroids, so if you find academia acceptable, JC will be preferable, but if you are more of a hands on/ learn by doing/ already found your passion, polytechnic might be a more suitable path for you.

But definitely, for now, it still seems that it is probabilistic more likely to enter university through junior college path than polytechnic. If you would like advice, feel free to contact me as I think it is pretty important and will be glad to help advice with no strings attached.
