This will be the easiest blog to write because I’ll just copy/paste one of the today’s email threads. I swear, I have not changed a word.
X. Modern Web Application development for Java Programmers: 1) Is this the first iteration of this course? 2) If no, do you have any testimonials from past students that you could share? 3) How often is this course repeated? I’m interested but concerned for my work load when the July course hits it stride. Thanks, X
Me.
1. Third
2. No
3. 4 times a year
4. If you can’t commit 20 hours a week don’t waste your money.
X. What an offensive response ! I don’t need advice on how to spend my money. I expected you to share the date of the next course so I’d be in a better position to make a decision if July or the next iteration would be better. You chose instead to be rude and in the process lose what was almost certainly a new customer.
Me. You call it rude, I call it honest. It’s OK to lose a customer sometimes.

Here is a student testimony: good course, worth of your time. And it is true that unless you spend 15-20 hours on your homework, it won’t be done. The more effort you put in, the more you get out of it. I personally work 45-50 hours week, so there is no way for me to complete homework, thus I was seriously considering quitting it after the second lesson, but then decided to stay… I will get what I can.
I’m a student of this course, it’s very useful for me. The pace is very fast, 20 hours is an honest minimum (I personally spend more). You have to study and complete homework unless your goal is to know just the names of technologies.
