I must say it'd be hard to study law without going over the cases because theres too much to always keep in your head.
Other subjects there isnt actually time to get through the full syllabus and be taught it properly, u get told it then your expected to learn it yourself, which gives you the choice of alot of homework during the year or a few days revision before an exam
My friend wants to be a midwife, she's been rejected from every uni she's applied to. Apparently they've tightened it up quite alot. She wanted to be a vet at first but wasnt getting the grades, so she thought being a midwife would be easier to achieve. Clearly not though.
