Should I sign up for June even though I'm not expecting to get a score I want.

I live outside of the U.S., so the only test dates I have left this year are June and October. However, I am flying back to the U.S. in August to see my family and take the August LSAT.

On my practice exams, when it's time, I got a 154. When it was untimed but I tried to stay close to the recommended target time (though I still went over on some sections), I got a 158. With blind review, I got a 168. My goal LSAT score is between a 168-170.

I find myself getting really stressed by even the presence of the timer. I'm wondering if I should take the June LSAT to hopefully get some nerves out of my system and get a feel of the test and give myself the opportunity to take the LSAT up to three times this year. However, I'm not expecting to get near my target goal. Also, I will be testing at a test center for June if I take it.

Thoughts? :"")
