Many companies and organizations judge for special awards. These judges are not included in the minimum of two. Besides special judges, many regular judges may need to get a second look at your project. The public is welcome to view projects after judging is completed and all during the next day. No, students should not come the second day.
Students are only with their project during the judging time.
Projects should be taken down immediately following the awards ceremony. Projects not taken down will be discarded. Every student will receive some sort of recognition. You may be surprised at what you win. No, if you have expensive equipment you should take it with you following judging.
