I am looking to apply for an LLM in the US next year. Problem is my grades are somewhat poor (my grades in my first law degree convert to approximately 3.1 on the 4.0 scale.)

I need advice on how to improve my chances. I haven't seen much discussion about the LSAT here. I understand that it is generally not a requirement for an LLM but if one takes it and hopefully gets a good score can it at all help with admissions? Any ideas?
