About John

Are you looking for help in Algebra, Geometry, Pre-calculus or Calculus? Let me help you master these subjects.

I am an experienced college level tutor, with experience as a peer tutor at the College of DuPage. While there I helped many students achieve success in their courses. I can help with common areas of trouble from simply understanding and interpreting the information in class homework to addressing specific areas of difficulty such as solving equations, factoring, graphing functions, working with trig identities, finding derivatives of functions and using them for problem solving, integration and its applications, and many other topics.

My approach is to help you identify and learn the information you need to understand your subject and connect it to the knowledge you already have, in a friendly, informal, intuitive way. I am knowledgeable, patient, and sympathetic to your struggles as a student. You deserve success for the hard work you've done, and I can help you achieve it.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

Computer Programming

I have experience as a programmer in multiple programming languages, including PHP, Java, Python, Visual Basic, C, C++, Javascript, and others. I have worked as a professional programmer in a PHP/MySQL environment maintaining custom CMS and e-commerce websites. I have also worked as a developer of custom Visual Basic apps to support internal data processing requirements at Quill, Inc. in Lincolnshire, IL. and other companies. I also have helped others learn PHP and Visual Basic and apply it to their own needs.

Microsoft Windows

I have extensive experience in installing, configuring, and using Microsoft Windows. I am A+ and Network+ certified. I have worked as a computer technician for Rain Trade, Inc. in Lake Bluff, Illinois, where I was responsible for troubleshooting and maintenance of the Windows based workstations, Servers, and Active Directory network. I have extensive experience with common Microsoft Windows applications such as Microsoft Office, web browsers such as Firefox, Chrome, and Internet Explorer.

I have experience maintaining, configuring, and using windows, including installing and removing programs, modifying various configuration settings through the control panel apps and other means such as editing the registry, maintaining computers in both a workgroup and active directory domain setting, and various operating system operations using Windows Explorer and the command line prompt.

I am familiar with MS Windows XP, Vista, 7, 8, and other versions (server versions such as Windows Server 2008 etc, and older systems such as Windows 98).

In my experiences supporting these system I have frequently interacted with users, training and tutoring them in the proper use of these systems.
