Is this a good thing to write in a resume?

Question

EDUCATION
2006 – 2007
SchoolName High School
• Currently enrolling Gr. 11.
• Courses in Chemistry 20, Physics 20, and Social 20.

Are the 20s really nessessary? Or should I leave them?

Answer 1

I would leave them out, because the person reading your resume will not understand them. Chemistry 20 in one school may be called Chem 1A in another. Just writing Chemistry is enough. Good luck!

Answer 2

I don't think they're necessary, because recruiters won't know what they mean. If it's 2nd level, then you could just say Chemistry 2 (for example).

Or, if the text you use says Intermediate or Advanced, then you can write Intermediate or Advanced Chemistry.
