Any advice as someone who has bad study habits, but planning to enter law school

Hello everyone! I am a gradwaiting college student, and I am planning to study law.

Lately, my parents have been pressuring me to take several law school entrance test. And to be honest hindi ko po alam kung kakayanin ko ba, especially Pag Sa Pag-aaral ng law dahil hindi po biro. Ako kasi yung tipong pa easy-easy lang na tao during my college years, at hindi gaano ka seryoso mag-aral, and sobrang sira ng study habit. What are your advices po for someone like me?

Maraming Salamat po!
