Testimonials

When I started working with Christian I was already doing well in mocks, but it wasn't reflecting on my official tests. With the classes I quickly realized that there were things that I didn't know I was missing in my preparation. I put in the hard work, but this time it was the RIGHT hard work.

I used the online platform to binge learn most of the tricks and new strategies in a couple of weeks while balancing one on one classes and a demanding job schedule.

Finally in just one month I was able to land a solid 49 in quant, and I truly believe that Christian's help and expertise was an important factor in achieving this result. I highly recommend him!

Christian is an excellent teacher, not only because he is an expert in GMAT Quant, but also because he really cares for his students and is always available and willing to help. His online platform was very useful to learn the theory and main techniques in a clear and structured way, and at my own pace. Then, during one-on-one classes Christian helped me to gain speed and confidence, by teaching me good tricks, short-cuts and simple approaches to solve questions faster. Most importantly, Christian was very understanding during the whole GMAT process; he shared lots of material to practice and gave me excellent advice and guidance along the way. I highly recommend him!

What makes Christian different (and great) is that he makes an effort to understand where you are struggling, which topics are your strength, and how you can improve. Through his teaching method, I raised my quant score from Q44 to Q49. If you are aiming for a top MBA program, I suggest you reach out to Christian.

Christian really helped me understand Probabilities and Ratios, my two weakest topics in math. He gave me good tricks to tackle these problems and lose the fear. Plus, he was very understanding during the whole Gmat experience and always supported me with additional material to study and helped me when I had any particular doubts with math problems.

Taking intensive classes with Christian, I was able to increase my quant score from 30 to 49 in two months! His methods and strategies really worked and helped me to master complicated subjects fast. I would recommend him to anyone who wants to score very high on GMAT quant.

Like for many people, the GMAT was a real challenge for me. In order to succeed in quant you don't only need to be dedicated and hard working, but you also need to dominate the techniques, tricks, and strategies to tackle every topic in the exam. All of that is taught by Christian in a very easy, simple, and efficient way. I recommend him 100%, he's a math expert and great teacher.

The classes with Christian have been very helpful to understand all the topics and increase my level in math. Christian is an expert in math and he can even explain the hardest topics with a method that is simple to understand.

Christian was incredibly helpful in strengthening my quant skills for the GMAT. Not only is he a brilliant teacher that works restlessly to break down concepts making them easily digestible for his students, he also gives valuable strategic recommendations that allow you to better approach the overall test. I highly recommend MBA Prep Tutoring to anyone interested in applying to a top 10 MBA program.

Working with Christian was a real pleasure. Since day 1 it was easy to tell he had all the knowledge and necessary tools to help you get the desired score. He had a thoughful approach for the whole proces and offered guidance in many aspects along the way (besides just math). 100% recommended!

Before I started working with Christian I believed that I was prepared and only needed to correct some specific aspects. But I couldn't be more wrong. The method on how to approach each specific problem and how to apply the theory were the steps that I was missing. 

My first contact with GMAT Quant preparation was through Christian’s online classes and 1o1 lessons.

Through the online classes, I felt very comfortable with this teaching method: structured topics and lots of exercises with clear explanations and helpful tips (which I think make the difference between solving a Quant problem correctly vs doing it in an optimum range of time). As I progress through the course I was able to notice how I was improving, and how know-how from previous lessons was helping me with further topics. Through his 1o1 lessons, I was able to polish how I solve and approach the different types of exercises. He focused on exactly which was my procedure and how I could optimize it to reduce the time I took to solve each exercise.

I definitely recommend Christian. The structure of his course, the clarity of his explanations (both through videos and 1o1 classes), and his accessibility to ask questions and support are key differentiators to his MBA Prep Tutoring course, and helped me reach a score of 49 in Quant section.

I was referred to Christian by a friend, and booked a meeting with him on the same day after being impressed by his website. I was pleasantly surprised by his availability and encouragement after I shared my initial results. During our one-on-one sessions he was able to identify my weaknesses. I believe this was a changing point in my GMAT prep since I gained consciousness of small mistakes and time-consuming tasks that were very specific to me and that I needed to avoid. When I saw my quant results I contacted him immediately to thank him. I recommend contacting Chirstian for guidance. It was truly one of the best decisions I made in my GMAT prep.

Christian was a great support during my preparation for the GMAT exam, not only for his methodology but also for the motivation and confidence that he gave me throughout the process. His methodology and his platform are 100% recommended, the videos are very easy to understand and you can quickly solve high-level problems in a more orderly and simple way. Also, he manages to provide you with the precise techniques and strategies that are needed to be able to optimize your time during the exam. I strongly recommend him as a Quant teacher. 

I had tried many math courses to prep for the GRE Quant section before finding Christian.  Taking classes with him was the best decision I ever made!

With his teaching method, I was able to detect tricks and techniques to answer the test. He has all the necessary tools to make studying easy and not overwhelming.  While he teaches, he patiently explains each subject with exercises and examples.

Something that I always appreciated was his encouragement to practice every day.  He is an excellent math teacher and kindly understands when math is not your strongest subject. Thanks to his excellent teaching method, I was able to feel confident to reach a higher score on the Quant section. 

Christian has various formulas that will help you approach the GMAT in a better way. For me, the GMAT, especially the quant section has been my Achilles heel. I have been studying with Christian's virtual classes and zoom meetings and they have helped a lot. I was be able to get the score that I needed. Thank you, Christian

Christian really helped me improve my quant score, his videos make complex topics very easy to understand and one to one classes with him were great!
