Instructions to run the tests

The JavaScript-HTML application "Interactive Tests" is updated in May 2023. In Windows 10 it can be run using Microsoft Edge and Google Chrome.

    Dear students,

    The Biochemistry teachers in our Department believe that instead of keeping the right answers in secret, it is better to have open and interactive tests, available for self-training and self-assessment. The number of items in the Biochemistry bank is big enough (more than 700). Thus a great number of different combinations of questions can be obtained for different midterm and annual examination tests.

    The interactive tests are in the form of a game and the challenge for you is to win this game. The tests help you to understand and learn the theory for the current and the final examinations.

    The test items cover most of the main categories of Medical Biochemistry. The types of questions are: multiple choice, multiple response, fill-in blanks, ranking, matching and questions, requiring a free answer. Excellent, wrong, incomplete, inexact and "no response" answers are distinguished by the JavaScript-HTML application.

    Below the list of the eight tests there is a table with links to the number of each test in three different modes.

  1. The questions can follow consecutively in the whole test (first mode),  consecutively in part of it (second mode) and randomly (third mode). Choose the number of the desired test in one of the three modes.
  2. If you choose the second mode, in the new window you should enter the number of the desired initial question and indicate how many questions you wish to answer. Then click on the "Beginning" button. In the third mode choose the number of questions and click on the "Beginning" button.
  3. The question is displayed after clicking on the button "Show a question". In the second mode the numbering starts from 1, hiding the real numbers of the questions. In the third mode the real numbers remain as they are - to demonstrate the random distribution.
  4. Input of answers:
    • If  the question is multiple-choice or multiple-response type, choose the right answers by clicking on the corresponding small squares on the left side. There may be more than one correct answer. You can cancel your answer by second clicking on the squares.
    • For the rest of the questions (filling-in blanks, ordering in logical sequence, matching between elements of two groups) enter a number or a letter in the corresponding rectangles on the right side according to the directions in the question.
    • Corrections are possible before clicking on the button "Evaluate".
  5. To evaluate the answer, click on the button "Evaluate". You will see below which of your answers are correct, wrong or omitted. In the left frame you will see the score for the question as an arithmetic sum of the weights of the chosen answers  (+1 for a correct one and -1 for a  wrong one). Given below in the left frame is the sum total of the test scores gained. Below in the left frame  is given the total cumulative score as a sum of the scores for all questions run.
  6. At any moment you can stop the test by clicking on the button "See your final score".
  7. The frames, dividing the screen into three parts are movable. You can move them with the mouse to see better the whole text, or illustrations or the score.
  8. If the test does not open, check it up and close previously opened windows with tests.You cannot run more than one test at a time.
