Please check the current guidelines for York University students wishing to study abroad, which may include taking a field course: http://yorkinternational.yorku.ca/global-learning
Many other higher education and environmental research institutions offer field courses. You may see notices for these courses posted at York. Some of these courses are taught by highly qualified researchers and some of them will, on assessment by the York Environmental Biology Advising team, qualify for degree credit (BIOL 400X) in a York Biology program.
Before you enroll in such a field course not offered by York or through the OUPFB, you MUST consult the Undergraduate Biology Office about whether its course curriculum will qualify for credit towards your degree program. For information about taking courses for credit at other institutions, review the university guidelines for Letters of Permission (LOPs).
