Some students may be having difficulty discerning the default font of Illustrator (Myriad) from the required font for Project 1.1 (Helvetica Neue).

Though it is slight, Myriad has a modulated stroke in comparison to Helvetica. This means that there is a slight thickness or weight variation in the strokes of the letters. Notice, for example, that the tops of the o's are slightly thinner than the sides.
Both fonts are sans-serif, but notice that some of the characters in Helvetica, such as the "a" have a very small serif that is the same stroke weight as the rest of the font.
Probably the most dramatic difference between the two is in aperture: on Helvetica, look at how much closer the terminal of the "a" comes to its own bowl, and the terminal of the "e" to its own eye.
The curves on Myriad are also much more gentle than Helvetica, which has pretty abrupt changes in direction.
That should help you identify the difference.
Changing fonts to outlines
If all looks well, on screen, but you simply cannot get your compositions to print out in Helvetica, select all of your text, and go to the menu Type < Create Outlines.
This will make your text uneditable. Be sure to do this only before printing, and undo it once you are finished
