I completed the course on R analytics, and I was very impressed with the content and the instructor, Dr Alvin Ang.

Dr. Alvin exudes passion in the field which really shows when he goes in depth on the courses he teaches. It is inspiring to be able to learn from his expertise. He relays his knowledge in such a comprehensible manner and also makes learning fun as he shows/explain practical examples which also increases students' attentiveness and share his love for the field. His ability to relate to each individual student was commendable, as he understood each students' unique needs and provided personalized guidance on how to apply the skills learnt from the course to optimize both in work and personal life. The courses which he led left me a lasting impression that I learnt not just the skills which the course entails, but also a sense understanding beyond that.

Overall, Dr. Alvin's expertise, combined with his ability to connect with students and guide them effectively, made the course truly worthwhile.

If you're reading this, I appreciate you for going above and beyond, and I feel that is what separates you from being a teacher and a mentor. A teacher follows a strict curriculum and ticks the boxes as per requirement, while a mentor is not limited to that, being more fluid and additionally guide students towards achieving their goals. Thank you for teaching and it has been an experience learning from you.

Dr Alvin Ang was my trainer for Data Analysis and Visualization with R course at Tertiary Infotech. He is a very knowledgeable and passionate individual in the area of data science. Dr Alvin can convey complex concepts in statistics in more straightforward terms in an engaging and fun way, which immensely helped me understand. He is also a great teacher who can answer all my queries and even go the extra mile to explain other things I need help understanding. Furthermore, he also shared resources and insights beyond the course syllabus, which was very insightful for me. From attending the two-day course, it was obvious that Dr Alvin is also well-versed in other data science tools beyond R. I recommend that anyone interested in learning about R or any other data science tool attend his courses. You will surely benefit a lot from his courses as I had. (Posted on 5/22/2023)

The mini exercises helped, can have more of that

Since it is expected that many people who have signed up for the course may be new to R, perhaps there could be a half-day crash course added to the course duration so that we could cover more or the actual course content at a more comfortable pace. (Posted on 12/8/2021)
