Probably not, especially if you did not receive a Form 1098-T from a qualified educational institution (with box checked that you are "At least 1/2 time student") and are only taking classes "once a month".
(If you did receive a Form 1098-T from a qualified educational institution (with box checked that you are "At least 1/2 time student", then you could be considered a "full-time" student)
Generally speaking, you are considered as a full time student if you enroll in school for at least five months in 2017. However, each school defines "full time" in its own way (usually in terms of the number of courses or hours). According to IRS publication 17, you are a full-time student if you are enrolled at a school for the number of hours or classes that the school considers full time. You must be full-time for some part of each of 5 calendar months during the year. (The months need not be consecutive)
For claiming the educational benefit purposes, full time is also equivalent to at least half-time that is if the student was taking at least half the normal full-time work load for his or her course of study. The standard for what is half of the normal full-time work load is also determined by each eligible educational institution.
