From my point of view, SBR is more challenging than P2 as the former requires more business acumen and the assessment of knowledge is deeper than P2's.
However, you could use some study aid to facilitate your revision.
I'd personally recommend you to use BPP Workbook and Practice and Revision Kit.
Also, you should have a look on resources provided by ACCA especially syllabus, specimen exam papers, technique articles and so on.

Finally, you could find some useful free lecture notes and videos via Opentuition.com
I hope above helps.
