On the website, it is written that the exams will be online: Exam dates 2021 | Institute and Faculty of Actuaries
Someone already answered the question, and quite politely too. https://www.actuaries.org.uk/studying/curriculum/life-insurance
Hi - I think the reference to 'paper-based' just means that the exam requires written answers (albeit now typewritten rather than handwritten!) as opposed to being a 'computer-based' exam using 'R' or Excel, as is the case for the earlier subjects. It is still the case for SA2 that you should only submit written answers (in Word).
