INSTUP

That inorganic chemistry in pharmaceutical universities is a fundamental subject, which is rich in what it means to successfully master other chemical and special disciplines.

The most important task is to learn and secure the most effective methods of control and self-control assimilated to the material of study. A number of traditionally victorious in chemistry with control methods (more precisely experimentation, independent and control work, sleep and writing), more and more vikoristovuvayutsya testi, tobto. standardized, as a rule, exchanged for an hour of testing for reverification of knowledge, reduce that skill.

The unparalleled advantage of the test methodology is efficiency, which allows the student to make adjustments to the learning process. The craziness of the tests in the bagatorase is more than that, as if the robot is disturbed by them, as if to correct the information, and actively її zagalnyuvate, reshape, stimulate the logical thought. It is not the fault of a robot with tests at any given time to turn into a “guessing game” game.

Tests are prompted however: before skin nourishment, several variants of treatments are suggested, in the middle of which, more than one is correct (or the most common). Starting to work on the tests, start reading the relevant material for assistants, lecture notes, laboratory journal. Conquer the necessary supporting materials: a periodic table of elements, tables of variability, influencing potentials, electronegativity of elements, dissociation constants of electrolytes.
