Although the two assessment challenges follow the same principles with common standards and are highly rated, there are very significant differences between the two assessments. We shall discuss these differences in brief details. 

SL20-General Challenge (GC-SL20)

This is a high standard SL20 assessment taken by anyone under the age of 20 years. The assessment challenge is taken three times a year in April, August and in December.  Each of these three session has only one sitting. The question paper has 100 multiple choice questions carrying one mark each and the paper is 2 hours long. Unlike the NPC-SL20, the GC-SL20 is relatively easy and less demanding. Results will be published within two weeks. In addition to the top ten prize winning candidates, all the students with a score above 95% will be recognized and the top three performing candidates will be awarded some special awards. The GC-SL20 cash prizes are relatives low valued and is very cheap to register for participation. 

SL20-National Prestige Challenge (NPC-SL20)

Although the NPC-SL20 is also strictly developed for children under the age of 20, it is a top-rated and a highly valued IQ challenge assessment. It is not just an ordinary quiz, but a battle of the mathematical minds. Unlike the GC-SL20 that is taken three times a year, this challenge is taken only once every year in December. The challenge has three consecutive siting sessions. That is to say, the assessment has three question papers: the first and second rounds are taken during the first week of December on the same day and the final session on a different day, normally in the following week. The NPC-SL20 sessions 1 and 2 are both multiple choice question papers carrying 50 questions each. The time allocation for each of these papers is 90 minutes. Only those who will succeed in session 2 will proceed onto the final session, session 3. Session 3 is considered the toughest session. It consists of 100 multiple choice questions marked out of 500 marks. Each correct answer carries 5 marks and 3 marks will be deducted for every wrong answer. It is a highly demanding exam. The results will be published in the same month, but the prizes and special awards for the winning candidates will be awarded in January of the next coming year. Only top three candidates will be declared the winning candidates. The cash prizes are very lucrative and the special awards are highly valued. In addition to these top three wining candidates, all the participates with an average score above 90% will be recognized and all the candidates with an average score above 95% will receive some special recognition. However, registration for participation in the NPC-SL20 is relatively higher compare to the former.
