I thought learning R would be difficult but the introduction was great and has given me hope that I can be good at R. Really loved how the videos were informative and easy to follow along. Thank you.

Hi! This course is just the simplest way I have found to understand R. Thanks a lot!

This course is fantastic! I can't say enough good things about it. There were a few basic functions that I had already learned in R but I had always struggled with retaining the information because I'd never quite understood the grammar around how to piece functions together. David breaks down everything into really easy to understand and digestible chunks. I was asked to complete an assessment in R for a job interview only 2 days after finishing this course; I was able to complete the assessment and was asked to progress to the next stage of interviewing. With a lifetime access, this course is well worth the money. I would 100% recommend this course to a friend or colleague.

WOW! Thanks, this was challenging. I am learning something new that I hopefully will retain.

Very good explanations in an entertaining way, I really enjoyed the course

Very easy to understand and a great introduction to R! It even was fun! Really recommend it.

After learning R through self-study and short courses, I realized my knowledge was fragmented—I understood pieces but lacked a clear conceptual map. R in 3 Months by David Keyes has been transformative: its well-structured videos, hands-on exercises, and live sessions helped me connect those pieces and finally see R as a coherent system rather than a collection of disconnected tools. It also helped me tackle a persistent challenge: forgetting functions and their underlying logic by showing me how to effectively leverage AI to refresh my memory and uncover unexpected connections. The support of Gracielle Higino has been equally invaluable, making the learning process both effective and encouraging.
