I'm 28 and just graduated with a BA.. will take the LSAT in June. I used to think my age mattered, not really. Everyone has a unique story, accomplish your dream to be an inspiration for others. Good luck :)
27 is not too late, and in the big picture, there's really no difference between 27 and 28. So, if I were you, I wouldn't feel like I absolutely had to apply this cycle.
