Quotas

My sentence:

-Students will be allowed to enroll in one course during the course adding period in May subject to availability of class quota.

Is my sentence correct? Do I also need to say QUOTAS, plural?

Add a hyphen to 'course adding'.

Add a comma afte

Students will be allowed to enroll in one course during the course-adding period in May, subject to space availability.

CliveI don't understand what you mean by 'class quotas'. Please explain.

um... is QUOTAS, in the plural form, wrong English?

In dictionaries, QUOTA is defined as

-the limited number or amount of people or things that is officially allowed

My opionion was, if there is one course, then we have one quota, say 50 people at most; if there

"Class quotas" is certainly possible (for more than one class) but "subject to the availability of class quota" is not correct. The quota determines how many students can enroll altogether. It's not an available quota that is necessary, but an available space.

OttoJDo you think my theory is OK?

The word "quota" is most often used in the context of immigration, racial anti-discrimination, import and export laws and voting. It is mostly used in a legal context (where there are quota laws) not a policy set by a school for classes.
It can be either a minimum or maximum number, as applicable by law. So a class quota

Thanks for clarifying that, A-Stars. When I was trying to think about what was "wrong" with the original sentence I got to the point where the word "quota" suddenly seemed totally unfamiliar to me, and I forgot that it often means a mandatory minimum. (For instance, someone in a piecework factory might well have a quota that they have to meet every day to retain their job.)

khoffThe quota determines how many students can enroll altogether.

Do you mean in an online system we can make a table like this?

Quota Vacancy
Engineering Course 130 30 (=100 students have enrolled in this course)

This is clearer to me:

Course Name	Maximum Enrollment	Currently Enrolled
Eng. 233	130	100
