Welcome!
The Center of Academic Progress (CPU, Centro de Progreso Universitario) was established in 2002 as part of the activities related to the Title V project, which ended in 2006. After this time period, the Center became part of the institutional commitment to support students and was appointed to the Office of the Dean of Arts and Sciences. Thanks to this effort, the Center still continues to offer academic support services to our students during their first years of college (first 72 credits).
The Center of Academic Progress works in coordination with the academic departments and the Dean of Arts and Sciences, as well as with counselors and subject coordinators, who serve as links between tutors and professors. Students who attend regularly will be evaluated based on modern educational methods, and will also be granted honor points that will be added to their grade in the course, according to the standards of each teacher (see additional information).
The CPU uses different methods to provide tutoring. Students receive the service in small groups where, in addition to getting their questions answered, they learn to develop and strengthen their teamwork skills, among other benefits. Tutoring services are offered in the fields of Mathematics, Spanish, English, Physics, and some Engineering classes as such as Statics, Computers, etc. These services are provided pending the availability of tutors.
The page for the Center of Academic Progress (CPU) is designed for its use by PUPR students. You will be able to view modules on course topics that will help you as a refresher; plus there are reviews classified by subject and links to tutoring services by other institutions. You can visit our subject index and use the review modules, which are listed by subject and are also linked under the syllabus for the the selected course.
We are located on the 3rd floor of Building M, Polytechnic University of Puerto Rico, Hato Rey, PR. Our tutoring service hours are Monday through Thursday, from 7:00am to 8:30pm; and Friday, from 8:00am to 3:00pm. Our office hours are Monday through Thursday, from 8:00am to 5:00pm; and Friday, from 8:00am to 3:00pm. You may call us at (787) 622 -8000 ext. 274, 331, visit us in office M – 305, or e-mail us at milmartinez@pupr.edu.
Sincerely,
Dra. Milagros Martinez-Roche, Director

Services
The CPU uses various methodologies to offer tutoring services to PUPR students. There are tutoring services on the subjects of Mathematics, Spanish, English, Physics, and some Engineering classes, such as Statics, Dynamics, and Computers, among others. These services are provided pending the availability of tutors.
These services are offered to students assembled in small groups where, in addition to having their questions answered, they learn to develop and strengthen their teamwork skills, among other benefits.
To receive the services of the CPU, you must:
- Be a regular PUPR student
- Be registered in one or more of the courses for which we offer tutoring services.
- Get formally registered for tutoring services during the enrollment period. (Enrollment periods are announced at the beginning of each quarter.)
Registration
To register:
- Visit office M – 305 during the enrollment period, which is determined at the beginning of each quarter.
- Fill out an application for registration for each tutoring service you want to receive.
- You must fully complete your application.
- Bring your properly authorized official PUPR registration.
- Submit your completed application so we can register your enrollment in our database.
- Once you have formally registered, you may begin receiving our services.

Honor Points
How to receive honor points:
You may receive honor points for regularly attending your tutoring services, at the discretion of your course professor. These points may be added as a bonus to your class grade. Allocation of points may vary according to the subject and criteria established by the professor.
To obtain honor points:
- Points are awarded by combining two criteria: attendance and academic achievement.
- You must be officially registered in the tutoring service.
- You must have attended your tutoring services more than six times.
- You must exhibit satisfactory performance in your tutoring sessions. (Demonstrate academic achievement.)
- The tutor will send a score report to your professor.
