CIMA – Operational Level studying more than 2 syllabus at a time

Hi All

From my understanding some people have managed to study 2 syllabus at a time i.e E1 alongside either P1 or F1 (as there’s no calculation involve in E1)

Can I get some advice from those who was able to do this AND work full time please?
And what resources did you have? I’m thinking of going with BPP On demand and purchasing Kaplan Exam Kits (unless I don’t need both)

Thanks
