The OLE indices are decent. You might be able to make better ones but that'll take quite some time. Either way, you'll have to spend a fair bit of time familiarizing yourself with whichever index you use (or alternatively just use the long version of the table of contents).
Past exams aren't available but practice exams are available to purchase online (in a format that prevents copyright infringement).
I've mentored high school students who were considering this program, and I like to think that I saved their careers. It is a huge money grab. I got into a heated argument once with an admissions officer from the program, who was telling high school students that Laurier was ahead of other schools in the "law" area, by breaking down barriers and creating a tailored partnership program that would allow them to bypass the numerous "barriers" in Canada to become lawyers in a quicker and easier fashion. And they were arguing that there is a demand for lawyers in Ontario/Canada and this program was created to help service that demand. Plus what else can beat the international experience of studying in the UK, right? Go figure.
It's incredibly sad how this program and the one at Trent (https://www.trentu.ca/futurestudents/degree/law-arts-law-business-trentswansea-dual-degree-llb-babba?target=undergraduate) were created to target naive high schoolers. I understand targeting university students, but children? Please.
This program is a massive money grab – totally not worth it. There is a chance you might not even want to be a lawyer by the time the Sussex part rolls around (as mentioned by @Turtles), and on top of that foreign degrees just aren't worth it, especially if you are still in grade 12.
OP's parents, for the love of God, please let your child attend an undergraduate institution and pursue a degree of their choice. If they want to pursue law, get your undergrad degree, get good grades, write the LSAT, and then apply to a law school in Canada if that is still what you want when you graduate.
Hey, I saw on your post history that you were a UWO student (I am as well!). Western doesn't have any letter grades on its transcripts but only percentages, so I was worried about how LSAC would convert my % grades into my GPA. when you were applying to US schools, did LSAC conversions screw you over or did they convert according to the link you've posted here? according to the link you posted a 80-89% at UWO is a 4.0, which honestly sounds a little good to be true. is the website link accurate? does LSAC really convert an 80-89% to a 4.0?
