Workshop Descriptions 
WORKSHOP DESCRIPTION
Some of the courses have mandatory workshops. The workshop, is included in the course, is STRONGLY RECOMMENDED to be taken by the students so that all the material presented in the lectures are practiced and exercised. Taking the workshop in addition to the course would be equivalent to physically taken the course at LSTC. The way the workshop course works is the instructor provides students with 68 workshops with instruction of what to do in each. Each workshop is described by the instructor and time will be given to perform each workshop by the instructor or independently by the students. Once the given time expires the instructor discusses the workshop, shows the results, and answers students questions. The students can talk to the instructor online or using phone or VOIP (the workshop course is very interactive with the instructor) at any time they desire. At the end of the workshop course the instructor provides all the solutions to the workshops in a pdf file. Some of the courses the workshop will be conducted by the instructor in a life manner.
