The topic that I will cover will depend on your need and I will tailor the lesson accordingly. I will help you understand any computer science topic completely and with ease. Topics that I can help you with include (but not limited to):

Programming in Java, C, C++ and/or Python
AP Computer Science (which is equivalent to a college level Computer Science 1 (a.k.a. CS1) course using Java)
Data Structures (e.g., linked list, binary search tree, balanced trees, hash map, priority queues, etc.)
Algorithms (e.g., searching, sorting, recursion, dynamic programming, breath first search, depth first search, graph algorithms, etc.)

My teaching style is "explain things as easy as possible" and some of the teaching techniques I use include: (1) breaking down a complex topic into smaller units and explain each unit independently, (2) using a familiar concept to explain new computer science concepts (e.g., do you know that computer memory is similar to mail boxes ?) and (3) using my own brand of unusual analogies to illustrate new concepts. When appropriate, I will also explain any prerequisite knowledge necessary that you need to understand  the topic.
