Should I study hand-drawing, pen-and-ink drawing, or quick questions during the summer vacation for my freshman year majoring in urban planning?

The pen drawings and markers you mentioned are actually a whole block design. Pen drawings mean drafts, and markers are used for coloring. You can also learn how to color with gouache.
