Frequently asked questions
How many dot com master problems can I solve for free?
583 questionsYou can practice all of them for free. Membership registration is not required, and it supports regular study, today's review, overcoming weaknesses, and mock exams with specified sets, question areas, and question levels.
What is the difference between ADVANCE and BASIC?
ADVANCE is 70 questions, 80 minutes, and has a total score of 1000 points, and depending on your score, you will be awarded either a single star (★) or a double star (★★). BASIC is 50 questions, 45 minutes, 100 points, and a score of 70 or above is required to pass. Since the question areas themselves are set separately, they are also recorded as separate grades on this site.
What is the format of the mock exam?
When you select a test grade, questions will be asked based on the actual specifications for that grade. ADVANCE combines 50 questions at the single star level and 20 questions at the double star level, scores each level based on the points you have (700 points/300 points), and displays whether it is equivalent to a single star or double star. BASIC is 50 questions, 45 minutes, and 100 points.
Is there a "choose the two correct ones" problem?
There is. It has been announced that there will be a mix of questions with multiple correct answers in the actual exam, and that the exam will be graded using a partial scoring system. This site also supports multiple-choice questions, allowing you to answer after you have finished making your selections, and if there is an excess or deficiency, the score percentage will be displayed.
Are the mock test scores calculated the same as the real test?
No. The official score for each question is not disclosed, so this site calculates the points for each level evenly divided by the number of questions for that level. The scale of the total score (1000 points for ADVANCE, 700 points for the single star portion) and the standard points required for certification are in accordance with the official certification outline. Please use this as a reference for learning purposes only.
Where should I start studying?
We recommend that you first check your current location by asking random questions, then narrow down the areas where you have a low percentage of correct answers and review them. ADVANCE has a required correct answer rate for each question area, so avoiding areas you are weak in will be a shortcut to certification.
Is it an official past question?
No. These are original mock questions created for learning purposes, based on published question areas and test summaries. This is not a reprint of an official question.
Where is my learning history saved?
It will be saved in the browser you are using (LocalStorage). There is no automatic synchronization to another device, and if you delete your browser data, your history will also be deleted.
