I have my lnat next week, I've been practicing for the past month or even more, im just worried bc im getting 23s and lower on Arbitio, but I got a 17 on the official lnat sample. I don't really count the sample cuz I was very tired with a headache and I had to repeat it midway since the website refreshed. but many say that the sample is easier than lnat. should I be worried regarding the 17? or should I only rely on Arbitio grades and practice?
