I disagree with other commenters. I would absolutely recommend limiting the CV to one page. I don't want to speculate, but as a 3rd year student, you probably do not have much experience to mention anyway... Therefore, I think your CV is quite loose and not really compact.
You need to tidy your CV and compactify it. For your case, your CV must have the following properties in my opinion:
- Contain every experience you have
- Be easy to read and skim; i.e one page
- Nice and simple layout
- Content must be short, descriptive and on point. CVs are not essays, but they are not lists of key words either.
Don't leave large margins, and don't leave much space between content. At the same time, the CV must be readable and organized, and when printed, the font must be easy to read.
If you did all that and you still end up with more than one page I would be surprised! Nonetheless, at this point you might want to consider more than one page CV.
