Never take the shortcut.
Computer programming is not about language per se. It is about intelligent use of language to implement problem solving techniques using computer, that is essentially what the aptitude test is about - to gauge how much of such quality you have. You cannot improve your aptitude by trying out all sort of aptitude tests. That is shortcut. Shortcut does not pay. The only way to improve your aptitude is through serious leaning and a lot of hands-on practices. I have some points to share:
1. From day one, cultivate a good programming practice where you can find a lot of good advice on the web;
2. Do not just read, do a lot of hands-on and experiments;
3. Never afraid of making mistakes, because mistakes help you learn correctly;
4. Always be ready to learn from others, as I believe no one knows everything.
5. When you are confident enough, embark on some serious projects.
6. if you encounter problems, always consult google first, all else fail, visit Code Project.
7. Last but not least, when you are ready, help to answer question at Code Project broadens your knowledge and skills.
