USBeyond 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!

USAwesome experience with awesome results This program really helped me do well in my chemistry course. Without it, I definitely would have done a lot worse. I really enjoyed how helpful everyone is and it made chemistry a more enjoyable experience overall. I highly recommend it.

USI cannot say enough about Stem Excellence! I cannot say enough about Stem Excellence Tutoring. Lori's program is top notch and alleviated so much stress for my pre-med freshman daughter. My daughter got A's both semesters in Chemistry 151 and 152. Having the group sessions really reinforced the lectures. Lori works non-stop doing many extra sessions if needed and is always there to answer additional questions. I can't say enough, this is money well spent! We are so thankful to be able to use this service again next year in Organic Chemistry!
