Very Helpful site

Hi all! I am a fresher from California I was an average student and desired to clear Oracle exam to get a good career. But, i was confused as i do not know coaching class. My teacher told me to use this site. She taught me how to use online site to prepare for Oracle MySQL HeatWave Implementation Associate Rel 1 certification. I gave online mock test regularly. Once, i was confident, i gave the actual certification exam and am happy with my hard work. I am waiting for result now.
