[top] Student Testimonials

Overall, I thought the class was excellent. Sasa was very adaptable to the changing format of the class -- given that the class was originally focused on a pure programming class and changed to more of a high-level architecture class.

Samson - T-Mobile

Instructor has very good knowledge and is able to reach out. Overall the course was really helpful to understand.

Priyesh - eTouch Systems

Great, fast paced class stuffed with information. If you're up for it, you'll get every penny out of your time.

Ted - Intermec

I had taken another class before with the instructor for this class, Aleksandar Gargenta, and he has demonstrated on multiple occasions that he is very well versed in the content he is presenting. I feel like I got a lot out of this course.

Andrew - Computer Sciences Corporation

This class was very helpful for me to learn the fundamentals of android application development. The course material was presented clearly and the concepts were defined in an understandable manner. I am excited to take what i have learned and start building apps! Thank you!

Chrissy - Tribal DDB

Great program, thanks!

Vicky - Netgear

This is a great "highly condensed" course for person even with little programming background, will look forward to the Advance class soon!

Jeng - Freeflow Hardware

Great class.

Jonathan - Symantec Corporation

This course introduced me to Java web development. Aleksander demonstrated solid understanding of the topic. I would definitely recommend the course to my friends and colleagues.
Sasa knew his stuff and was able to answer all the questions he was being hit with. He did not preach the material to us but made sure we understood the whys of what was being taught. I wouldn't mind coming back for additional training or even having onsite setup.

Aliza - American Student Assistance

Overall the course was great. The instructor really knows his stuff. I definitely learned a lot in just a week. Hope this is the beginning of great things!

Don - L-3 Communications

This was a great training. The instructor was very well prepared and during the week he was able to keep the pace of the course at the right level.

Alexandru Catalin - Product Architecture

The method used to teach concepts was very excellent. I liked Sasa's way of presentation. Recommend the course.

Jagadeesh - Fujitsu Siemens Computers, Inc.

The amount of stuff to be covered in this course is quite too much, but instructor covered pretty much all. The time can be extended of this course to cover it better. Amazing Course!

Bhagyashree - Xerox

I found there was very little that could be done to improve this course, especially given the beginner level, the pace was just right and the amount of material covered was quite broad. I learned a great deal more from this class than I expected, especially given the very short term nature of the course. I really feel I was given a good fundamental understanding of Java. The instructor was clear, concise, worded himself clearly and unambiguously, and rigorously pushed the class to apply good coding practices. I would definitely take this course again if I had to do it over again.

Ignas - Xerox

Overall very good traing. As per the pace, it was fast paced, but was ok as there were so many topics to be covered.

Sweta - Fujitsu Siemens Computers, Inc.

Sasa was an excellent instructor and very patient with our many work related interruptions!

Brett - SkillSoft

Wide range of experience with students in class but material was well paced.

Fantastic course! Sasa knows so much that we need more than five days to cover the material for the class.
