<p>I was wondering how long is a year of classes. For example one of the prerequisites for my major is a year of biology. How long is that exactly, is it 3 units, 4 units, two semesters, can anyone help?</p>
<p>It is a two semesters or 3 quarters that go consecutively… the units would depend on your school but in order for it to be a year of X course it occurs in sequence basically, meaning you can not take the second semester of BIO until you took the 1st.</p>
<p>Thanks a lot malishka :)</p>
