3.10. Essential Skills List¶
The following lab skills are really life skills and students will need to learn as many as possible to be effective in a prototyping laboratory environment. It may also be useful to refer to the Topic Area Guides section and the essential skills posts on the F14 course web site.
Following each recommended skill is a very rough list of links to tutorials; probably many will be obsolete by the time you read this.
