Your BCPM GPA (sometimes called a science GPA) includes all Biology, Chemistry, Physics and Math courses taken as an undergraduate. On the AMCAS application, you will be asked to classify your courses in one of 20 categories. These include:
The terms asphalt shingle and composition shingle are general terms for the same thing. The term composition is used because the shingles are a composite product made from either a fiberglass or a cellulose mat, and asphalt and minerals, as opposed to a single material, such as wood shingles or clay tiles.he term composition is used because the shingles are a composite product made from either a fiberglass or a cellulose mat, and asphalt and minerals, as opposed to a single material, such as wood shingles or clay tiles.
A square of shingles weighs 250 lbs. to 400 lbs. depending upon the type of shingle (see below). An important thing to keep in mind is that many roofs have multiple layers of shingles, so you must factor that in when determining weight and choosing a dumpster. For example, a 20 square roof with two layers of shingles will actually produce shingle waste equal to 40 squares. Know how many layers of existing shingles are on your roof prior to ordering the dumpster to ensure you choose the right one and avoid having to get a second dumpster later.
