Our goal was to give our kids access to great tutors to increase their chances of receiving merit…read morescholarships. Both of our kids were tutored by different instructors at Moser and both had a GREAT experience. Scott asked a lot of questions about each student to understand their disposition, the way they learn, how much pushing they needed to study, etc. They were matched with very different instructors and both were patient, respectful, and clear in their teaching. Going into the college prep season with our older student, we were all a bunch of nerves. However, during the tutoring process, we collectively relaxed because our son became confident in his abilities to take the tests effectively. Both of our kids' scores were impressive, much higher than before the tutoring. As it turned out, they both did receive merit scholarships at their desired universities. Even if they had not, I think the confidence it gave each of them was well worth the price.

My son improved his score 200 points from his PSAT. He went from a 1280 to a 1480. We are absolutely thrilled. Zack did a terrific job with my son, he was patient with just the right amount of pushing my teenage boy. We will definitely use Moser again for our second son.

I would give Cameron a 10 if I could. I found him on Craig's List and he responded right away to my…read morerequest for help. Here's the scenario: Fall 2019 semester with my third attempt at passing the required stats class for my degree, This was literally the very last class I needed. If I didn't pass this time, I was not going back. My university was out of state, my class was online and while there was an instructor, he was more of a moderator. The platform was Pearson MyStatLab. I am not the brightest light in the shed when it comes to stats and my light was getting dimmer and dimmer with my pre-Cameron tutor. Just like this was my third attempt at the class, Cameron was my third tutor and finally, "The One". My first tutor wanted to just show me everything on his phone. The second tutor had children I could hear fighting in the background. With Cameron, even though we were online screen sharing, and on the phone, there was never any background noise. If I needed a visual, which was quite often, we would use Scribblar. There were instances when my brain just came to a screeching halt and my head would hit the desk, but Cameron with the patience of Job, would wait for me to come up with the solution. When it just wasn't there, I would tell him, and he would guide me to the answer. We stayed on task. We got the work done. He very patiently waited for me to take screen shots so I could use them as visual aids. He sent me tips through e-mail. I passed my third exam, even though I'm sure I stopped breathing at some point before that exam, and the class even after I failed the first two exams. Here's to you Cameron with my eternal thanks. I will never forget: "If the p is low, the null must go." You're the Best!

We are very fortunate to find Cameron as the math tutor for my two sons. Cameron has been my son's…read moretutor for two years. He is very professional, patient, organized, and detailed. He came to each class well-prepared. He has the ability to explain complicated problems in an easy way. He knows the subject very well and is always willing to tailor his classes to each student's special needs. He is also very knowledgeable and can teach any subject from math, physics, and chemistry, to computer science. He takes the tutoring job very seriously and took special classes from CU so he can be well prepared for the job. We tried several different tutors. Cameron is clearly the best.
