​In terms of learning something that's actually useful in your life, it's true that studying Spanish for a couple of years (and never continuing on to fluency) is a waste of time.

But if the time and effort you devoted to Spanish study did help lead to a degree or certificate, then, yes, your degree is something that you probably value and find useful in your life. 

If there is another value to studying Spanish for one or two years (and never continuing on to fluency), please contact us and let us know what you think.
