Hello, friends! I have been a professional for 8 years. While preparing for the LEANITL certification exam, I came across the wonderful site certfun.com. I shared this with many of my friends here in Germany, and they told me that it is a popular site for exam preparation. I initially thought it must be some tutorials, but I was wrong. The site offers numerous mock tests to sharpen skills for the actual exam, which impressed me greatly. I opted for the premium membership, and voila! Through regular practice on the site, I achieved a good score.
