MaxCompute SQL window functions were brutal for me on the ACA Big Data Certification Exam because questions often present subtle changes in partition and frame clauses to flip results, so you might be asked which clause produces a moving average versus a cumulative sum. Focus on partition by, order by, and frame semantics with sample queries until the outputs are obvious; I passed the exam and thanks Pass4Success for a compact question set that sped my prep.
