Beyond my expectations, wonderful chemistry tutor!!! I am writing this review as a student who worked with Dr. Lori Culberson as my tutor during the spring semester of my chemistry 151 class at the University of Arizona. I had lost confidence in my abilities and was frustrated with my test grades despite my study efforts in the class. From the first session, Lori made an immediate impact on my understanding of the materials. I was able to message my questions to Lori prior to our sessions and she was always prepared and knowledgable on the specific topics so that the session time was always put to its best use as we went over content that aligned exactly with my chemistry 151 course. Lori was articulate, friendly, encouraging and patient as she worked with me during the spring semester. The written recaps/notes and topic reviews that she provided after each session were like an additional tutoring session in themselves. I could write notes on the recap and refer back to it at school when needed. In the end, I was able to raise my final grade and finished with an A and Lori’s tutoring played a significant role in this outcome. This was my first attempt at using an online tutoring platform like Stem excellence and I am fortunate to have found Lori. I would recommend her without hesitation and I will continue to work with her as I navigate my future chemistry courses!

Phenomenal This really helped me through a really tough semester. The Key Topic videos were the best feature, and the live lectures were really helpful and important for me as well. This program might have been the difference between two letter grades in my chemistry class.

Dr. Culberson Review Dr. Culberson was an amazing asset for me taking Chemistry 151 and 152 at the university of Arizona! She was always there when a question came up, and shows passion in what she does, everyday!

The website was so self explanatory and… The website was so self explanatory and of course all of the resources I had were great! I couldn't have done chemistry without it!
