movie clips

I esp liked the movie clips and the relevance to the concepts.

The movie clips inbetween the course helps to remember terminolgies better.

The movie clips also makes it easier to understand, that was great.Thank you very much.

He makes it very easy to understand, plus the movie clips & illustrations help explain the concepts in a fun and entertaining manner.

His movie clips he used to juxtapose his points were an added bonus.

He showed movie clips in his lecture videos and related it back to the content, it really helped me to retain the concepts I've learned in the tutorial.

I also thought the course was very well organized and made good use of movie clips throughout to illustrate different points relevant to the course.

Understanding that this is a very basic level course, the use of movie clips and some over simplified examples can be condescending.

I also like the movie clips that keeps the lessons interesting.

I love those movie clips he incorporated in the course.

Thanks I really liked the course and the way videos/movie clips were used to explain the concepts was simply great.

Some good movie clips so that a person can easily understand and relate to.
