Oh yes, law is certainly way more mentally exhausting than history, at least for me. I can remember every small detail in the War of the Roses or WW1, but when it comes to administrative law, shit is hard to remember I wish there was an easier way to study law but there isn't ;_;
I am currently (re)studying law (civil procedure and criminal procedure) too, for my entrance exam at uni for Master's Degree. I literally cannot wait for it to be over to take a month long break 2
All my respect for lawyers for having learnt administrative law XDD the complicated language they use, there being always exceptions in every article, a thousand deadlines to remember… ugh…
I think you would have been a good historian History is like remembering a story but with more details, and being able to make a relation between a historical source (a text, an object, etc.) and what you’ve been “told”, and make your own conclusions out of the comparison. It’s an amazing thing to study, what a shame people don’t care about it because it doesn’t make money.
Good luck in your exam! I will also take a very long break after the examinations there is even a game about hominid's evolution, called Ancestors, that I definitely want to play once everything is done XD.
Btw, we don't do any exam to study a Master's Degree we use the global grade of your degree to make the selection.
