There is no preferred order to the different computer classes. We only ask that one be able to handle a mouse and also; that a basic class should be taken before an intermediate class of the same name, meaning Basic Word should precede Intermediate Word. It depends on the background skills of the individual and personal preference as to which type of class they wish to take first. Some people need or would like to learn the word processing skills in Word over the spreadsheet skills taught in Excel, or have more of an aptitude for typing, arranging, cutting and pasting words, paragraphs and sentences (Word) over adding, multiplying and subtracting household budget costs (Excel). The only order suggested is the order you wish to take them. Thank you for asking ASKCPL.
