How hard is the course
In highschool I was never good at English but I'm definitely keen on putting my head and improve it. I heard it's constant essays after essays.
From what I understand, there will almost always be an essay component to law (in terms of law school). But I think the % weighting of the essay component is usually less than that of the problem solving component. For example, in our torts assessments, the problem solving section (which is not an essay) constituted 65% of the mark for that assessment, while an essay critiquing a specific part of the law only constituted 35%. So I wouldn't say it's 'constant essays', but bear in mind that essay writing is a part of law, albeit you definitely do not need a passion for english. But good writing skills does help a lot.
What's the Job prospect
When I graduate will I definitely get a job instantly?
Like the others have said, for a career in law specifically, job prospects are not the best. It's very competitive to say the least. However, in reality law is a pretty good generalist degree that a variety of employers value, so you can use it to your advantage to get into a non-law job. So if you want do go down the non-law path, there are a variety of opportunities that you may have access to. I think like with a lot of other jobs, you can't guarantee that you'll 'get a job instantly', however, if you do well at uni and have so extracurriculars then there is a good chance that you can get a job straight out of uni. But again, I'm not really sure.
How much reading is there
Do they expect us to read at home?
I'm pretty sure the volume of reading just continues to increase. For me, first year law was a big shock in terms of the amount of reading. For some subjects, it's just reading case after case. I found it quite daunting but over time my case reading skills developed and it became easier to really decipher the key findings of a case.
In light of the above, only study if you have some sort of interest in it, and you can see that it could be valuable in the future. It is definitely not a degree that will guarantee a secure line of employment, or salary.
