Fundamental Chemistry
Solving problems from the Medical University of Pleven book is an online based tutorial that helps students to prepare for applying medicine in Pleven Medical University. In addition to the tasks some basic theoretical material is included, allowing more thorough and complete understanding of the material necessary for application in medical universities. By solving specific tasks the discrepancy between the amount of material taught at school in Chemistry lessons and the amount of knowledge required for students of medicine is more or less compensated. These tasks can be a good educational material for all applicants for medical universities.
The content of the material, on which tasks are based and their relevant decisions entirely cover the program for science test that includes:

• Atom structure - the nucleus, isotopes and isobaric; Main features of the electron, basic rules for filling the atomic orbit
• PERIODIC LAW AND PERIODIC SYSTEM OF CHEMICAL ELEMENTS - Periodic law and periodic system from modern point of view, Atomic properties
• Chemical connections - Types of relationships, intermolecular interactions, Valence and oxidation;
Thermo chemistry
• oxidation- reduction processes – Characteristics of the oxidation- reduction processes, electrolysis;
• Speed of chemical reactions - Chemical kinetics, mechanism of chemical reaction
• Catalysis - Definition, basic concepts, Types of catalysis, mechanism of catalytic process;
• Chemical equilibrium - reversibility of chemical reactions, nature and characteristics of the chemical equilibrium, factors affecting the chemical equilibrium;
• SOLUTIONS - Disperse Systems, Properties of solutions; Essence of dissolution, solubility, factors that determine it;
• Colloidal-Disperse Systems - General characteristics and types of colloidal-disperse systems, Properties;
• Theory of electrolytic dissociation - Electrolytes and nonelectrolytes. Mechanism of electrolytic dissociation; Degree of electrolytic dissociation and factors that determine it. Hydrogen index; Hydrolysis
• CHEMICAL COMPOUNDS CONSTRUCTION THEORY. STRUCTURAL THEORY - Basic principles of the structural theory, carbon chains and structural formulas; stereochemical theory; Isomerism - structural and spatial;

• Alkali. Alkenes. Alkyl - homologous series, isomerism, structure, physical and chemical properties. Obtaining

• ARENA - Benzene - structure, physical and chemical properties, homologues

• hydroxylated derivatives of hydrocarbons. Alcohol and phenol - Definition, classification, names, isomerism, saturated univalent and multivalent alcohols and phenols

• Carbonyl derivatives of hydrocarbons. Aldehydes and ketones - Definition, classification, homologous series, names, isomerism, obtaining;
• Carboxylic acids - Definition, classification, names, saturated fatty monocarboxylic acids

• Carbohydrates - General classification; monocharbohydrates , dicharbohydrates and polycharbohydrates
• Amino- acids - Definition, classification, designation, construction, physical and chemical properties. Obtaining.

AMINOKARBOXY ACIDS - Definition, types, names, isomerism, structure, physical and chemical properties. Importance.
.The purpose of creating this material is to help prospective students for medical courses at universities and to compensate the missing parts, which have not been given at high school course in Chemistry, and to provide the necessary material for application in medical universities.
The material of solved problems in chemistry for the Medical University of Pleven is applicable only in the forms of elective or free elective courses in Chemistry, only in Bulgarian schools where these forms exist.
The task book with solved problems of the Medical University - Pleven is unique in content teaching material, which does not exist on the web. This material helps to prepare medical students taking the exam in Chemistry. The decisions are covered extensively, giving all theoretical knowledge necessary for a student to apply successfully and solve the problems. All tasks are designed keeping the following algorithm: a concise, in essence, solution of the problem is given at the beginning, and then there is further clarification and extension of the decision. Thus, prospective students using the decisions can learn or simply check their knowledge.
Another advantage is that the solutions are offered free in the Internet, which makes the preparation of candidates a matter of desire and mental capabilities. The necessity of such material in the Internet is shown by the number of visits to the site where decisions have been published - more than 16 500 visits for 2 years from the beginning of the initiative. It is especially valuable that decisions offer knowledge which the student applicant must have to solve tasks at the exam without having the need to consult any other textbooks
On the other hand the decisions also have some weak points. Some tasks are too long as a volume and there is a possibility for the prospective student to choose what task to present at the exam. This threatens the most important in a task not to be selected and displayed.
Another disadvantage is that a not well prepared candidate can memorize solutions and submit them to the test. This calls into question the possibility the brightest candidates to be selected for students.
A technical disadvantage of the decisions is that they cannot be printed, and you can work with them only online.
It is too hard to speak about the scientific value of a learning material because at school well known information is taught and the decisions cannot deviate from them. The new moment in this form is that it provides an opportunity to learn chemistry by solving problems, which is a much more efficient method and leads to long lasting knowledge. The scientific level of knowledge in the decisions is high, often much higher than the State Education Requirements curriculum educational level, but they are consistent with the level required for admission at medical universities.

The pedagogical value of the solutions consists in the fact that they not only provide an opportunity for acquiring knowledge in Chemistry, but also develop skills for solving problems on the required materials for applying medicine. Through the decisions students can learn to negotiate or to test their knowledge and skills. The high professional level of the decisions, their readability and graphic design, the correct Bulgarian language in Chemistry make them invaluable in the process of students’ preparation in medicine, not only to the University of Pleven, but also for the other medical schools in the country.
