Learn SQL — one of the most in-demand data analytic skills today.As a previous Professor and now a Statistics/Analytics content manager for an education tech company, I use a teaching method that makes it super easy for students to learn. I teach SQL in a practical way so I explain concepts with examples, then you have an opportunity to apply what you’ve learned through exercises and further test your knowledge with weekly challenges.WHAT SOME OF MY STUDENTS SAY ABOUT THE COURSE:”It was a great course and very easy to follow especially for someone who had no experience in SQL. The examples given were simple and Dr. Cas breaks it down really well so you can understand better. She walks you through all the different queries thoroughly and also writes down some helpful hints if you get stuck. She was also very attentive when I got stuck on one of the challenges and reached out to her one late night. She helped me understand it better by giving me more guidance and helped me think outside the box.Overall, this was a great course to take and now I have another skill under my belt all thanks to Dr. Cas! Thanks for everything!”- Karla Flores, Senior Financial Analyst, Adobe (California, USA)”Excellent course and terrific inputs about every query. Majority of the job interviews that I appeared before this course had questions on SQL and I used to mess it up since I didn’t have my basics strong.This course not just helped me with the basics but also with the advanced concepts. It’s absolutely brilliant. I just feel completely charged up to attend any DS interview where SQL is a skill set that is asked. My motivation was not to give any chance to the interviewer/recruiter is to not provide any more opportunities to them to reject me and this helped me at least get to that stage. Rest of the outcome depends on the practice that I do. Only need some practice on the Data Cleaning section else I think I am prepared from an interview standpoint. Thanks for all the inputs and support Ava.” – R Suraj Kumar”This was my first time taking an online data analysis class outside an academic setting. I worried about how the design would work for me as a working professional and if it would enable me grasp the material, but I must say that everything about the online course was smooth, convenient, and enjoyable.The concise tutorial videos, quizzes with solutions and availability of the instructor, made it easy for me to understand the topics. The method, order, and scheduling were accommodating and in my opinion, makes it convenient for anyone, anywhere to take the course, and of course, the content was very useful to me.I’m glad I took this course and I will strongly recommend it and others to follow, to anyone trying to develop more skills for data analysis. “- Clare Ofodile, Project Manager, Quality Assurance and Research Development Agency Nigeria (Lagos, Nigeria)”I like this course as it is very easy to understand and relevant for a beginner like me. I wish I could have some more courses like this one. I really enjoyed it and I started to like SQL more. A big thank you to my teacher!” – Ana Rotari This instructor is highly effective and efficient in getting the critical knowledge across. Unlike other courses, this one did not drag. Time was well managed with the instructor’s teaching approach. In just three and a half hours, this course can be a career changing investment. – Jose Floresca Jr. “This course sparks my most interest in SQL and you MUST take to get strong foundation in SQL. Teacher Ava provides a very organized and informative course which is worth best 5 ***** (stars). And more than that, she always be there to support you to clarify your confusion. Believe me, after this course, your level of confidence improves a lot and exceed your expectation. For me, I’d like to attend more SQL courses from Ava in next levels. I hope she will have some good news.” – Dannie Le
