Hello!  My name is Dr. Geoff A., and I have been helping students (dare I say) enjoy math for over 20 years.  While I may be new to TakeLessons, I am definitely not new to teaching, tutoring, mentoring, and encouraging.

About 20 years ago after receiving my PhD in Math, I became a professor and taught just about every math course offered - from Algebra to Statistics to advanced proof courses along with graduate level courses.  My students consistently commented on how approachable I was and how I was able to make difficult topics easy to understand and complete.  While there I even tutored a gifted elementary school student, helping her master 8th grade math while she was in 3rd grade!

After about 10 years, my wife and I wanted to volunteer our time to help with relief work abroad.  Unfortunately, this meant I had to give up my position at the university, but the joys were definitely worth it :)  While abroad, I began tutoring math online - helping both high school and college students.  They too commented on how I made them feel less nervous about math and how I gave them the confidence they needed to ace their exams.  I even helped those with special needs to reach their goals.

In short, I love math and really enjoy helping people understand it at all levels.  I've worked successfully with student of all different backgrounds and comfort levels with amazing results.  I hope to work with you next!

Dr. Apel has consistently delivered stellar tutoring in statistics, math, and probability.

I've been taking lessons from Dr. Geoff since 2015 to prepare for actuarial exams. He has helped me tremendously with understanding not only how to work actuarial problems, but also the theory behind the process. Dr. Geoff is very patient and knows how to explain problems in different ways to make sure students have a clear understanding. I would highly recommend Dr. Geoff!

Dr. Geoff is the go to person if you are looking to improve mathematical comprehension. He has mastered not only the complex application of numbers and equations, but the art of teaching material to students in a way that suites each individuals unique needs. I used Dr. Geoff for two years while studying for the preliminary actuarial exams and I successfully passed with great marks. I continue to pass along his information to anyone I encounter that is looking for the extra boost, because his methods are worth every penny spent!! I am so grateful for finding Dr. Geoff and I know others will feel the same

Dr. Geoff is an absolute legend and I highly recommend him. He helped me with studying for Exam FM, an actuarial exam that focuses on advanced financial mathematics. The exam was highly focused on applied techniques and I come from a background of theoretical math, so it was difficult for me to grasp concepts from an applied approach. He was able to put things into a theoretical perspective for me and he taught me to think about the material in a new way. He never once made me feel stupid or inadequate. He simply asked lots of questions to get a feel for my skill level and learning style and he was then able to adapt his teaching style to my needs. Math can be a brutal subject but Dr. Geoff is very good at making it approachable and even enjoyable. Again, I cannot recommend him enough and I will absolutely be going to him for help on future exams.

I cannot endorse Dr. Apel more strongly.  

I'm a mid-career Physician Executive who engaged Geoff to bring me through the long and challenging process of actuarial certification (ie - some very advanced mathematics focused on probability, statistics, and finance).  I personally hold degrees in engineering, medicine, and business from MIT, Dartmouth and Rutgers.

In all of that education, Geoff stands out as a superior teacher.   If you are reading this you likely want to know about his efficacy to teach and not his flashy publication history.

Although I am working with him on some rather advanced concepts - he is able to break things down into very basic, yet solid, ideas in a very approachable way.   Once he is assured you have a firm command of the concepts - he then uses those solid building blocks to construct very elaborate ideas which enable students to go very far conceptually.    This ability to focus on BASIC  fundamentals is a quality which I've found distinguishes the finest schools paradoxically.

Of course, his professionalism and knowledge base are beyond question and he operates at the highest level in that regard.

I hope to stick with him throughout the lengthy process of actuarial certification.  That said, his style is such that he would also be exceptionally well-suited for even high school students who may need some help, encouragement, and confidence building.   

I'm not ashamed to say that it's very refreshing when - even at my age and level - someone makes things simple and builds your self esteem.

I could not endorse Dr. Apel more highly and I hope that my personal narrative and experienced  perspective lends credibility to this review.  If you'd like to verify the authenticity of my comments you can find me on Linked In at adowidowiczmd.

Sincerely, 
Anthony J. Dowidowicz MD MBA

Dr. Geoff is an amazing tutor! He is patient and breaks down to a level that is clear, concise and precise. Currently doing probability with him.

We extend what we did in the previous video on Boolean values using the compound logical operators "and" & "or".  How do we use and write them in a JavaScript statement? Find out in this video.

07 - Compound Logic

What are Boolean values, and how are they used in JavaScript? Find out in this video.

06 - "boolean" Data Type

In your first coding challenge, you are asked to write a line of JavaScript that will produce a random integer 1, 2, 3,..., 10.

04 - Coding Challenge 1

In applications you will often need round numbers and generate random numbers.  So we discuss a few of the main methods for doing that: Math.round(), Math.floor(), Math.ceil(), & Math.random().

03 - Rounding & Random 

In this video, we look at some of the common Math methods you will encounter.  We also show how to use the MDN Docs (https://developer.mozilla.org/) to learn about these and other properties and methods.

02 - Math Methods

In this video, we introduce the "number" data type in JavaScript.  We also show how it is a little different from other programming languages.

01 - "number" Data Type

In this video we explain what JavaScript is and why it is so important.  Additionally, we introduce the Chrome console, which will be used in all of the subsequent lessons.  Please watch this first so that you can code along with us in the most popular programming language!

00 - Intro PLEASE WATCH FIRST

At last, we finally talk about how to add colors, sizes, and other formatting to elements of your web page.  Don't miss this important lesson!

HTML

12 - Styles

In this video we use the site https://picsum.photos to insert random photos of specific sizes into a website.  

11 - Images

Comments are an important part of every program.  How do you add comments in HTML, and why is it important to do so?  Find out in this lesson!
