I 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!

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!

I Can't Thank This Program ENOUGH! I started taking Chemistry at the University of Arizona for the full year of 2021-2022. I was taking both 151 and 152 along with both having labs. My first exam in the Fall Semester of 2021, I completely failed it. Rushing to my parents, I bawled my eyes out completely and felt so belittled by such a bad grade. In doing so, my family reached out to Stem Excellence and found a tutor for me. Her name is Lori and she absolutely changed the way I thought throughout this class. This was not just a simple "ask questions, and you'll get answers," type of format. It was basically another class with less than 20 students who got to learn the material twice, but this time, from her own perspective. From being with her for only a couple weeks, I managed to get the worst grade of my life to almost acing my second exam. She goes off the syllabus the professor's use when it comes down to what lessons we're learning and explains them thoroughly instead of skimming through. The time this program puts into their students is absolutely amazing. They even have "Check-In," calls where you can update your tutor with how you're feeling and doing. I promise you, this was definitely worth it in the long run and helped me get the grade I deserved. Can't thank you enough Stem Excellence!

Awesome 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.

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.
