The real estate asset may also appreciate or depreciate as determined by a town’s assessor.
A certificate program requires an enrollee to complete set of categories of courses and an average grade-point average (GPA) of at least 2.5 in these courses. This project is to build an independent blockchain-based tool so that any student interested in this certificate program can use this tool. A student enrolled in the certificate program can self-check their progress through the program from anywhere.
