which most definitely add up to his convenience. 
Harshit learn about LEARNOUT, a free social learning network of university and school students. 
It offers a platform for its users where they can engage in activities like sharing study related 
materials, counseling or simply connecting through a vast network of existing users from around 
the world. Within a small time span of two years, more than 80,00,000 students registered for 
the website and they use the website on daily basis. The distribution of the students in different 
age groups was graphically presented and he got inspired as he thought himself that maximum 
number of children of his age is gaining from this site. 
Figure 1: Histogram showing the number of students using learn-out in different age groups 
The website offers user generated contents in 7 different languages including Italian, English, 
Spanish, Polish, Russian, Serbian and Portuguese. The website is directly operated from its 
respective regional head offices thereby providing a direct approach to the users. Learn-out also 
has its free application available for all android devices. The website also has a dedicated 24/7 
support team to assist the students in their matters. He surveyed a number of people and 
recorded his finding on the percentage of users using this site in different languages: 
Table 1: The percentage of users in different languages of LEAROUT is given in the table below: 
Language Italian English Spanish Polish Russian Serbian Portuguese 
Percentage 
of users 
11 57 6 4 10 9 3 
He also discovered a site name TWOWAY which provides its students with a different approach 
towards studies. It offers an interactive way of studying where students get to create and 
animate flashcards. The website currently has about 1 million study content authored by the 
students. The website also conducts different quizzical campaigns for the students and tracks 
the progress of its users. The issues on which the campaigns were conducted are presented in 
the form of pie chart. 
Harshit also got a platform to spread awareness of the issues which he has to record in his 
project work given by his teacher. He could collect the data globally and interpret it from 
different perspectives. 
Figure 2: The pie chart shows the campaigns conducted on TWOWAY in different subjects. 
Mathematics was troubling him and he needed a special assistance in various concepts. He 
received many resource materials to gain more knowledge and achieved higher level of learning. 
The site name TROUBLE BUBBLE was the answer to his queries. TROUBLE BUBBLE offers a very 
interactive way to the students looking for answers to the distressing questions. They can ask 
questions directly from academic experts through their vast network. The following data shows 
the number of question asked by students between 2:00 pm to 9:00 pm. 
Table 2: The table below shows the average number of questions asked at different hours of the 
day on TROUBLE BUBBLE.

Harshit was pleased to know that he has the facility to get immediate answers to his queries 
though his site.
