Should I do APM or AAA if I just passed SBR?

Originally was going to do APM next since the syllabus is quite small so the exam might be doable for September. However, I’ve heard that there is some overlap between SBR and AAA. Given that I still have retained some knowledge from SBR, should I do AAA next? Is studying and practicing mock exams for AAA doable in 6 weeks?

I also passed SBL ealier this year and am aware there is some overlap with APM.

Also I’m thinking of using Ben Wilson for AAA, should I use his revision core package through his website or use him through Viva Tuition. Seems like Viva Tuition is more comprehensive in terms of tution and revision core is more focused on exam technique.
