I purchased the self-study online course of BCS Business Analysis Foundation from Training ByteSize and after several months studying (I ate the theory first), today I easily passed my exam due to the well structured course with theory and practice parts much orientated to the exam, not in general about the analysis. Every section had many review questions that looked very similar to the ones I had in my exam. Aditionally, there was exam simulator with hundreds mockup questions. I liked it and deeply reccomend Training ByteSize for all business analysts willing to be BCS certified.
