How to prepare for the USE in chemistry: the structure of work, the semantic blocks. How to prepare for the USE on chemistry from scratch
Today we will talk about how to prepare forUnified State Exam on Chemistry. First of all, it is necessary to study codifiers and specifications posted on the official FIPI website, understand the structure of the work, and then systematize their knowledge. It is worth noting that if you are preparing for the exam from scratch, then you need to begin at least one year.
ЕГЭ in Chemistry
The final work contains 40 tasks, of which35 require a choice of answer (1 part), and 5 - deployed (part 2). The difficulty level is also different: 26 refer to the base, 9 - to the average, 5 - to the increased. Solving the most difficult problems, graduates are obliged to use the available skills in an unconventional situation, to systematize and generalize knowledge. Questions that require a complete answer require you to find cause and effect relationships, formulate and argue the answer, characterize the properties of substances and solve chemical problems, and perform calculations.
The tasks of the Unified State Exam on Chemistry cover four main content modules: the theoretical foundations of chemistry, organic chemistry, inorganic chemistry, methods of cognition in chemistry, chemistry and life.
The work takes 180 minutes.
Unified State Exam on Chemistry 2015 In the new academic year, innovations in the structure of the work appeared:
the number of jobs is reduced to 40
there were only 26 basic level questions (for a single choice)
for questions 1-26, only one digit is required
for passing the test you can get 64 points
The problems of finding the molecular formula of substances are now estimated at 4 points.
As before, it is allowed to have DI Mendeleyev's periodic system, in addition graduates are given tables of solubility and stresses of metals.
Preparing for the USE in Chemistry
To be ready for certification in chemistry, it is important to systematize the knowledge gained. The best way to do this is with the following tools:
