Harvard Law Graduate Who Helps Students Score Higher than 173 on LSAT
Because many of the top law schools use rolling admissions, you should take the LSAT during your junior year or the summer before senior year so that you can get your application in early for one of such schools. If you are applying to lower ranked schools, you can take the LSAT during your senior year. However, senior fall is pretty busy with applications, so you might be happier if you have already nailed down the LSAT score you need. Preparation can begin on a limited basis any time after January 1 of your junior year. Don't wait until summer if you need a good enough score by early fall!
