PLT is a 6 month course of practical legal training facilitated by the Law Society of South Africa. If completed successfully, then you would only need to do 1 year of articles instead of 2.
I would suggest that you apply for admission during your last semester of studies should you wish to go this route.
Honestly, I myself am not entirely certain of the course itself but I have received correspondence stating that we will receive course material at registration.
Please e-mail me on firstname.lastname@example.org
and we can keep each other in the loop once we start with our respective courses. Look forward to hearing from you.
