My brother pursued his BA LLB from KSLU and here are some things that helped him score well in his exams. 

• Before the examination makes a complete list of all the important topics. Also, make a synopsis on them. It’s easy to remember bullet points rather than paragraphs. 
• For each question that you are attending make you mention atleast one case law. Case laws will help you score better.
• Answer your questions strategically. Don’t just write the answers. Work on making your presentation better too. Try to make points and tables, in the answers. 

Doing these can certainly help you score well.
