Felsic lavas (dacites or rhyolites) tend to be highly viscous (not very fluid) and are erupted as domes or short, stubby flows. Viscous lavas tend to form stratovolcanoes or lava domes. Lassen Peak in California is an example of a volcano formed from felsic lava and is actually a large lava dome.
Most psychology degree courses want you to have a science related A level, so anything from biology, physics, chemistry, maths or psychology. I just finished a psychology degree and I didn't do biology at A level.
Step 1: Earn a Bachelor's Degree. A bachelor's degree with some exposure to psychology is a prerequisite for graduate school. Students may want to major in psychology in order to take as many classes as possible in the discipline. A major in a related subject area, such as biology or chemistry, is another choice, as long as some psychology coursework is included.
