I have a conditional offer from KCL. The doubt being, my condition states, must secure a first class (60%) in taught law subjects. I'm currently pursuing my BA LLB ( 5 Year Course) from India. Does my condition essentially mean that ONLY my LLB subjects will be considered? Or the marks attained up til the 5th year will be considered? Also, we have practical subjects in two semesters. Will the marks for those practical subjects be considered or not?

Congrats on your conditional offer! Based on what you describe of the condition, it sounds like only the LLB subjects (i.e. law subjects) will be considered. I think the practical ones will be too if they are law subjects (e.g. things like moots). It's probably best to verify with KCL's admissions for peace of mind and more clarity though.
