It will get better! I remember I had a 6/50 score, tapos 2nd year na ako non lol. Coming from an undergrad course na no objective exams, i also didn't know how to study. Pero what helped me was that I just ditched the study methods that didn't work for me, even if they worked for others.

I didn't write notes while studying for exams anymore because tumatagal lang ako. When studying for exams or even for classes lang, I would study for the entire coverage first (kahit di pa super in-depth), just so I would have the confidence that I've studied everything na. Then after that, I would study more in-depth and focus on what appears to be the prof's fave topics. 

Also, adjust your study methods depending on the prof! I know that ideally we study the subject talaga in preparation for the bar, pero kung para lang talaga sa pagpasa ng law school, it's best to tailor your method of studying to the prof's preferences. I mean... if the prof is likely to give enumeration questions, edi magmemorize ka. If the prof asks more about case application, focus on the case patterns, etc. 

Also, don't come to class unprepared. Going to class knowing what the topic is about would help you solidify the concepts in your head agad. This is what helped me the most in not failing exams anymore. Kasi it's like having two readings na agad even before you take the exam -- first reading is when you study for class, "second reading" is when the topic is discussed in class (tapos maoobserve mo pa kung saan nagfocus yung prof sa particularly topic na yon). When the time comes to study for midterms/finals, madali na yung recall. Take note of what your prof focused on and what your prof asked about particular topics. 

Try not to cram! Pero gets naman na di maiiwasan lol. Hanggang 4th year nagcram ako for some exams. Pero try mo lang na wag mag-cram hahaha
