1) Maintain a high GPA
Most successful law school applicants have strong undergraduate academic records because it is a primary factor in most admission criteria. Therefore it is best to keep your GPA high to remain competitive.
2) Gain a decent LSAT score
The second factor in most admission criteria is your LSAT score. Almost all law schools require this test, and use it as a predictor of how successful you would be in their program. Having a good score can thus bolster your application.
3) Strong ‘soft’ factors
Your GPA and LSAT score are ‘hard’ factors, however, some law schools will look at other ‘soft’ factors. These include significant extracurricular achievements, work experience, disabilities, exceptional circumstances, etc. Some law schools require interviews, letters of recommendations, and personal statements to understand the applicant as a whole, rather than just numbers.
