## Testimonials

“Upon meeting Shahab, I was struggling in statistics and it was apparent that I needed extra help outside of office hours with my prof. I am fortunate that Shahab's strong background in math and statistics as well as his familiarity with UBC courses really helped me in my statistics course. Shahab is a patient individual who takes the time to review complex concepts at a pace that worked for me. It is through his adaptability and interest to help his students that he makes our sessions interesting and approachable. Throughout our sessions, we would work on concepts in full before jumping to the next section. He prepared detailed chapter outlines which gave me an additional study resource that better prepared me for quizzes and problem sets. In my experience of being tutored, Shahab brought clarity to a subject that I was not confident in and allowed me to stay on track with my peers.”

Monica Y.

"Shahab tutored me for STATS 302 at UBC, a course that I think most tutors don't cover because it's a bit more advanced. I reached out to him with an emergency, since I had just failed the midterm I needed what was essentially a rescue for my grade. I was stunned with the level of mastery that Shahab had over the content, additionally, he was very patient with me since I was struggling to understand some basic concepts. I always looked forward to our sessions where he was incredibly well prepared with summaries of each section and problems selected from past finals that related to those sections. In the end I managed to finish with a B- thanks to Shahab!"

Danny I.

“I highly recommend Shahab to anyone who is interested in getting tutoring. It has been a pleasure to work with Shahab and refresh my statistics knowledge. If in need, I would do it anytime again without hesitation. Shahab is a very intelligent tutor, who wants his students to understand the concepts and succeed. He is very kind, always on time, and engages vividly with his students. He listens to your problems, and tries to find a way to solve them, even if it means for him to invest time to understand the issue more in depth. I am convinced, that he will be a great teacher and mentor for many more students throughout his career, and I recommend him warmly. You are lucky to be Shahab’s student!”

Ebru I.

"Shahab helped me with intermediate quantitative method statistics course (STAT 3223 @ Langara College). I hired Shahab because I was struggling with the course and was hoping to finish the course with at least a C+ letter grade. Shahab was able to explain the material and breakdown the concept very effectively. My final grade was an “A” and I was short by 3% for an “A+”. Shahab is very knowledgeable in statistics. He is flexible with his schedule and meeting places and his charges are very reasonable. I would recommend Shahab to any STAT student for tutoring and I give him an “A+” rating."

Yogesh P.

"Shahab is the best private tutor/teacher for stats I have ever imagined to have! He is a life-saver. He taught me the same material I was having issues to understand at college, and magically it all made sense overnight. He explains in a easy way that the whole comes together and I nailed my midterm and final exam. Thanks Shahab for all the effort you put in our classes to teach me, and make me have a great final grade!...By the way, I was almost failing the course, and he saved me. Next course is ahead, and I am already looking forward to having our skype classes. Thank-YOU!"

Cynthia H.

"There are no words to describe how grateful I am for the support I receive from Shahab at Hoops Tutoring. As part of my degree, I had to take a quantitative research course. Despite having completed the first course, the second part of the course required me to use a lot of statistics, which was beyond my understanding. It would be an understatement to say I was overwhelmed. I searched for days for a tutor, and with only two days remaining for an assignment due, I came across Shahab's website Hoops Tutoring. He was quick in responding, very organized, reviewed my assignment before our meeting and was very patient. Shahab broke down the various tests to a level that I understood and answered all of my repeated questions without judgement or frustration. I usually do not write reviews; however, I feel so strongly about the tutoring services I received from Shahab that I needed to share with others looking for a tutor. I have already shared his contact information with friends enrolling in the same course in the fall and spring, and if you are looking for someone knowledgeable, patient and honest, then Shahab is your guy! Thank you again!"

"Shahab is an exceptionally bright, patient, and dedicated tutor who has an innate ability to make the most complicated of content easy to understand. He was my tutor for graduate level multivariate linear regression and he was incredibly flexible in his tutoring approach, using multiple methods for explaining the same concept (i.e. graphically, verbally, and using equations). It was commonplace for Shahab to go above and beyond, evaluating the course content prior to our meetings, and following up with information that he thought would be useful between sessions. In addition to the stats content, he also has an extremely solid knowledge base in R. I learned more from him than my stats professor and because of Shahab I feel confident in my understanding of regression analyses and R no longer feels like a black box. I recommend him hundreds of times over, I wish I had the opportunity to work with him earlier ! Worth his weight in gold, honestly."

Samantha F.

"I feel very fortunate to have had Shahab as my tutor for my return to a graduate-level study. Having been away from quantitative research for many years, I was faced with having to both re-learn and learn anew a set of statistical methods appropriate to my research design. Shahab immensely cut down the amount of time it would have taken for me to do this on my own. Instead of wading through resource after resource, Shahab guided my vision and helped me to thoroughly understand the relevant statistics needed. He also was able to effectively introduce me to the R software environment and help me through sticking points in the learning process. Thanks to Shahab's ability to explain core ideas and underlying logics of both stats and R, I now have the statistical know-how and software abilities to do much on my own. He was agile in his answering of my diverse questions (using concrete examples when needed), was able to identify what I needed from the outset and always ensured to be as prepared as possible."

"There are no words to describe our family's gratitude to Shahab for the help and support in Statistics he provided to my child this year. Shahab went over and above, not only patiently teaching and explaining the material, but also in his encouragement and trying his best to be available whenever needed. Statistics is as much of an art as it is a science. Shahab has an extraordinary way of being able to break down the most complex ideas and concepts and simplifying it into a way that a student looking at this for the first time can readily understand. He is patient, kind and encouraging, and is able to build confidence in his students, thereby enabling them to start off on a strong foundation that they can then take off and independently think for themselves! After all, is this not the signature of a great teacher? That he or she equips every student with the skills and strategies they need to stand on their own feet and excel. Shahab, thank you so much. The year would have been very different if not for your help. You are an extraordinary teacher and any student would be privileged to have the chance to work and learn from you."

Lynette N.

"Shahab is an extremely patient, comprehensive and knowledgeable teacher. Thanks to his thorough understanding of Probability, I was able to ace my first statistics course at UBC, despite having little to no prior knowledge or experience. I wholeheartedly recommend him to any other math or statistic students."

## Exam Prep. Strategy

I usually use the following recipe when preparing students for an exam:

#### Theory Review

I will summarize the course material for the student and go over some of the 'theory' basics they need to know for the exam.

#### Categorization

Exam questions come from premeditated "question categories." I will identify & provide the student with a list of these.

#### Practice

I will guide the student through several practice exams to make sure they are used to answering questions under time pressure.

Categorization is the most important step. Once a student understands how to approach each "type" of question, they are likely to be able to answer any question on any exam, even if they have not encountered any of the specific questions before, even if they have a poor understanding of the theory, and even if they have not done any of the practice exams. Thus, my main focus will be on Categorization.
