It’s honestly a personal decision that varies from person to person. I decided to not reapply 9th because i did not want to have the feeling that I “wasted a year of my life.” However, that is just me, but there are a lot more benefits to reapplying 9th. First off, friends and social stuff will be MUCH easier, and you all will have the "we are all in this together vibe.’ Huge disadvantage for applying/going into 10th, is that you are tossed in and expected that you perform on par with the returners, thus, most people’s GPA will suffer their first term.
