CFAI is still making the 2016, 2017, 2018 AM portion of the exams along with answer keys available. I’m inclined to use them in study prep, even after the 2020 curriculum update. Obviously not all questions will be relevant for 06/06/2020 exam.
You can find them here once you log into your CFAIaccount:
CFA Institute / CFA Institute Programs / CFA Program/CFA® Program Registered Candidate Resources/Level III Essay Exam
The links to the exam can be found towards the bottom of the page.
Is anyone else using them? thoughts?
