There's a common belief that hard work is the key to success. However, when it comes to passing the PMI-CP certification exam, I found that working smart made all the difference. Rather than solely focusing on the syllabus, I chose to attempt PMI-CP practice exams. This approach not only helped me clarify my doubts but also ensured that I didn't miss out on any crucial topics. By practicing smart, the fear of leaving important points behind didn't trouble me at all.
