GRE Chemistry Syllabus

GRE Chemistry Syllabus

The GRE Chemistry Test is one of the seven disciplines offered in the GRE Subject Test. The duration of the test is 2 hours 50 minutes and 130 multiple questions will be presented to you. You can access the periodic table printed on the test booklet along with a table of information which contains various physical constants and a few conversion factors among SI units. If needed, additional values of physical constants are mentioned along with the text of the question. The test emphasizes the below mentioned four sections equally. Though it contains few mathematical calculations, you do not require any calculator or table for computation.
