A collection of source codes that I wrote in VB 6.0, ASP.NET, PHP, C#.NET, VB.NET and JAVA in a course of my career as web developer and software engineer that I would like to share to my fellow programmers. Some of the codes here is not my original work that I found over the Internet and Books while I'm learning how to program. I hope you find my work useful in your learning in programming. Please share my work to other people also who interested to learn the basics of web development and programming. Thank you very much and Happy Productive Programming Everyone.

Part 2 – Train4Aptitude

Aptitude problems are an important part of competitive examinations. Aptitude Problems on concepts of time, speed, distance manifested either in the form of Problems on trains or stream and boats or simply a generic example involving cars, bicycle etc. The key to solving the problems is effectively visualizing the scenario given, and translating the problem that is described into equations which could then be worked on to solve problems.

Following are this week’s videos to help you train yourself on aptitude.
