SBRAre my Kaplan books outdated? SBR & SBL 2019.

There have been a number of changes in the syllabi of the above subjects since you obtained the above books. If your books cover the 2019-20 syllabi for the above subjects, there will have been three updates to these syllabi since that time by time of September 2023 exams- 2020-2021, 2021-22 and finally 2022-2023. I would advise you get new material. At least obtain updated practice and revision guides which you can use in conjunction with the notes and lectures on this site.
