Substitution of Subjects
Substitution of subjects must be based on at least one (1) of the following conditions:

The student is pursuing a curriculum that has been superseded by a new one and the substitution brings the old curriculum in line with the new
There is conflict between a required subject and another subject.
The required subject is not offered.
Every petition for substitution must:

Be betweens subjects carrying the same number of units (or the substitute subject may have more number of units), and 
Be recommended by the adviser and by the heads of the department concerned 
No substitution shall be allowed for any subject prescribed in the curriculum in which the student has failed or received a grade of ‘5’, except when, in the opinion of the department offering the prescribed subject, the proposed substitute covers substantially the same subject matter as the required subject. 

All applications for substitution shall be acted upon by the Dean. In case the action of the Dean is adverse to the recommendation of the adviser and the head of the Department concerned, the student may appeal to the Vice Chancellor for Academic Affairs, whose decision shall be final.
