Software Reviews & Feedback from Students and Science Faculty

"BioTutor®, ChemTutor®, and PhysicsTutor® are the best educational software packages I have seen for science students. They help students of all ability levels to get better grades with less total studying time. They help students to learn more efficiently and more effectively."

"ChemTutor® Excalibur is awesome! I am definitely impressed with the LEARN and EXPLANATION options. With step-by-step explanations and easy-to-read print with clear, helpful diagrams, ChemTutor® Excalibur is the secret to conquering college-level chemistry without hours of reading wordy textbooks. And with its user-friendly interface and clarifying graphical aids, it's way better than textbooks. Now that I have ChemTutor® Excalibur, I could pretty much throw away my textbook."

Einstein"ChemTutor® Excalibur is going to help a lot of students. The LEARN and EXPLANATION buttons definitely do their jobs. The explanations are thorough and break down the principles into comprehensible pieces."

                          Sarah C. Jones
                          Carleton College


"ChemTutor® Excalibur is excellent. It teaches with correct, concise, and marvelously clear explanations of everything you need to know in Chemistry. The diagrams, tables, and definitions that ChemTutor® Excalibur provides are so clear, focused, and well written. They get right to the point and explain concepts better than my slick, overpriced textbook did. I recommend ChemTutor® Excalibur to anyone who is currently taking, or plans to take, a chemistry course."

                          David E. Blum
                          Grinnell College

"ChemTutor® Excalibur covers all major topics covered in college chemistry in good detail. The LEARN and EXPLANATION features are perfect. Having 'learn' and 'explain' as separate features allows the program to cater more precisely to a student's needs."

                          John G.A. Benton
                          University of Virginia


"ChemTutor® Excalibur cannot help but bring better grades and understanding in Chemistry. It gives helpful, concise explanations of answers to its probing questions. The visuals used in many of these explanations allow for ready assimilation and are presented in a way that it is almost impossible not to understand."

                          Robert Caughey
                          Haverford College


"I think that anyone could get an easy A in college-level chemistry with the help of ChemTutor® Excalibur. The LEARN and EXPLANATION features really bring studying to a new level of excellence."

                          David E. Berman
                          University of Pennsylvania

BioTutor®

"I worked with BioTutor® over the weekend before a major test in AP Biology. I can definitely say that BioTutor® was significant in my getting the best grade in the class. It especially helped me to get a stronger grasp of all the facts and concepts and to gain a better understanding of how they all fit together."

                          Eric Klose
                          12th Grade AP Biology Student
                          Downingtown, PA


"I've been using BioTutor®, and it really helps. It's pulled up my grade from a B to an A. I think it helped because it gave me a good idea of questions that could be on the test and if I didn't know a question, then I would go back to the book and re-study that section in the chapter. The only reason I was getting a B before was because I didn't have very good test scores. However, on my most recent test (on Genetics) I got a 37 out of 35 points (including a 2 point extra credit question) because I had reviewed that chapter in BioTutor®. Thanks! It's really helpful!"

                          Laurel Van Gemert
                          9th Grade Biology Student
                          Portage, MI


Methane "I'm happy to report that my student who had been failing science just scored a 93% on the Skeleton & Muscle test. We employed BioTutor® using both the Tutorial and Test Simulation modes. As a result, he got an A-. That's quite an accomplishment for him, because he had sort of given up on school. I am very happy to report this news to you, and I feel that your software was a contributing factor in this situation."

ChemTutor®

"ChemTutor® is great! It really helped me to further understand the material."

                          Dana Mincer
                          10th Grade Chemistry Student

"I used ChemTutor® and got a 750 on the SAT II in Chemistry!"

                          Jeremy Saul
                          10th Grade Advanced Chemistry Student
                          West Chester, PA

"I used ChemTutor® last year while I was taking Chemistry. It helped me to better prepare for tests. ChemTutor® was especially helpful in studying for the final. It took me less time to study because I didn't have to go through every chapter in the textbook. With ChemTutor's Semester Exam option, I could cover all of the topics at once. Thanks!"

                          Sarah Speth
                          11th Grade Chemistry Student
                          Orchard Lake, MI

"ChemTutor® is a blessing. I've always been a good student, but when I got to high school, math and science hit me hard . . . especially chemistry. I found that doing ChemTutor® 2 or 3 days before every test improved my test scores by almost a letter grade. I'll never be a chemist, but at least now I feel more confident walking into chem class everyday."

                          Sarah Hudson
                          11th Grade Advanced Chemistry Student
                          Kennett Square, PA

"At Westtown School we have all three ScienceTutor™ applications on our school's computer network and most of our students also have the software on their own personal computers. My own students have found ChemTutor® to be extremely helpful for studying and preparing for tests. This past spring, all of my first-year chemistry students had access to ChemTutor® to help them prepare for the SAT II in Chemistry. I was very pleased with how well those students performed on that exam . . . better than any previous group of students I have ever taught." The following table shows their results:

SAT II (Chemistry) Score
% of Students
700-800 38%
600-699 29%
500-599 33%
below 500 none

PhysicsTutor®

"PhysicsTutor® is immeasurably helpful in preparing for any kind of physics test or exam."

                          Jonathan Evans
                          12th Grade Physics Student
                          Texarkana, TX

"PhysicsTutor® helps students to learn physics and to test their knowledge of and ability to apply physical concepts. The tutorials cover both the quantitative and qualitative aspects of physics. PhysicsTutor® goes way beyond the plug-and-chug approach that too many courses employ and allows the student to get a feel for the subject matter. Almost all of the tutorial questions that require calculations can be done without a calculator, so PhysicsTutor® is an excellent studying tool for the SAT II subject test in physics."

                          Martin Lodish
                          Science Department Chair
                          The Hill School

"PhysicsTutor® is excellent. The graphics are good, it is easy to follow, and it has good content."
