I'm really amazed at you John. Finishing everything in 1.5 years. you got accepted by colleges, right? What was your GPA? And which college accepted you? What was your DAT score? I really am sorry for asking so many questions to you, but I really am relieved that I am not the only one who decided to choose this path of study.
		
		
	 
I will say this: at the beginning, I was older (matriculated at 25 accepted at 24), but I still did all my college/prereqs in 1.5 years.  I didn't know what I wanted to do with my life, was getting married to a hygienist, went and watched her employer (dentist) and thought that I could do this for the rest of my life.  So I went to work.  
G.P.A 3.3 (sci and overall maybe overall was a 3.4)

So, it is possible.  I haven't had a summer off in forever, say there is no way I can specialize straight out of school (I want some fun time and money 
🙂), but I am glad I did it.  
My only piece of advice is do everything you can to make yourself stick out.  Maybe going through school quickly is your "thing."  Shadow a ton, and research the schools you interview at; it is nice to go and interview and have Brian (at Temple) know your name, tell you that you have asked "excellent" questions and compliment your dental knowledge. 
😀   
It is so competitive, you have got to use every advantage you can get.  At Temple, they received over 4,000 applications and they didn't think they would even look at the last 2,000 received because they already had too many qualified applicants.  Everybody has a 3.3 gpa and 19 DATs.  So you need to make yourself stand out in other ways that lets the school know you are right for them.  Good luck.
