* Course Availability: The specific courses you need might no longer be offered. Contact the institution directly to inquire.
* Credit Transfer: The institution you plan to graduate from needs to accept the credits from the correspondence course. Their policy on accepting transfer credits, particularly from correspondence courses and after a significant lapse in time, will dictate whether this is possible. You'll need to contact the registrar's office at your school to confirm this.
* Policies on Prior Learning: Some schools have policies about how long ago coursework can be to be considered for credit. They may have a time limit.
* Institution's Policies: Each institution has its own rules and regulations. Some may have stricter requirements for transferring credits from correspondence courses or after a long break.
In short, it's highly recommended to contact the registrar's office at the institution where you're aiming to graduate *before* you enroll in any correspondence courses. They can confirm if this is a viable option for you and guide you through the necessary steps.
