Introduction
The reputation that online education has created for itself has
extremely fuelled and stimulated its expansion at an exponential
rate. The skepticism initially attached to online mode of study
has terribly dwindled as more and more evidence emerge of its
convenience and effectiveness as compared to face-to-face
mode of education. The aim of this paper is to look at some of
the benefits online education offers. Online education is
offering many necessary things compared to traditional
education. It has more flexibility in cost-effective choices and it
gives students the opportunity to review class materials at any
time they want.
First body paragraph
Even if some schools are offering loan to some students, online
education still have better deal. Traditional courses are not
offering loan to all students. Moreover, if it does, students
would suffer to pay the payments after they graduate. Also,
Universities take an interest on each student loan, which would
make it harder for them to pay it back some of whose interests
are inflated according to the performance of the federal
economy. According to the US News (2010), most of
Universities Students are receiving Merit Aid. However, if
someone needs a scholarship, he/she will to be subjected to
strenuous procedures and unnecessary bureaucratic processes
that would eventually discourage a good number of applicants

2. and the lucky few have to suffer to get it. Most of the
Universities are only offering scholarship for certain amount of
people. In scholarship.com (2009), they show how student can
get academic or Merit scholarship. This is in an outright
violation of right to education for the students who may not be I
a position to afford the extent of fee. In academic scholarship
you need to get a high grades and it should be in the top five to
ten percent of your class. Also, Merit scholarships are almost
same as academic scholarship, but also it can be given to a
candidate displaying artistic or athletic excellence or sometimes
a combination thereof. We can infer that only small percentages
of the whole universities who get benefits from scholarship. For
majority of all students, online courses are better than
traditional schools. Friedman (2012) shows that online courses
only cost $100 if it’s not free. However, the tuition of
traditional courses at Stanford University is over $40,000 per
year. We can tell about the huge different between these two
courses. There is no way that a normal student can afford the
tuition for traditional Universities. Students are not only
suffering from universities tuition. Aspillers (2008) shows that
online education may help students to save their money by
elimination the costs of transportation, babysitting, parking and
other expenses incurred by attending class in traditional sitting.
Moreover, students would not have to waste their money to buy
a hard copy of the textbook. Online education is not requiring a
physical textbook, which might cost triple of the online
requirement.
Second Body Paragraph
Many people believe that taking notes during class is more
effective than have the notes online for students, but let tell you
why this is a wrong idea. The online notes can be always online
and there’s no way for students to lose it. Moreover, it’s more
accurate because it’s directly from the professor. During class
students may miss some of the important information, but online
courses everything will be given from the professor online.
According to the article; Ten Advantages of face-to-face

3. classes” (2013), students would be able to take notes and they
would learn more in face-to-face classes because students are
able to see the act of the professor and express it in their notes.
What they don’t know is that online courses have more to do
with taking notes. They can see the lecture in videos. Moreover,
they are able to repeat the videos as many as they want in order
to understand the given notes that are already uploaded online
from the professor. According to Alto (2012), it shown that
online courses are having high quality way of teaching and it
has been developed for a long time. It’s time to change. The
videos and notes in online classes have been developed in order
to be the easiest and most accurate way for students. Students
can review their notes and lecture at any time they want. They
do not have to be forced to attend lecture at time they don’t feel
they want to study. Online notes allow students to click it and
go over it whenever they are ready to study.
Conclusion
Online studies and education enables students to manage their
time in a constructive manner. Study materials are ever
available for reference always. Assignments, homework and
projects can be done with information being sourced from
updated sources. Also, It has now been made possible for an
individual to complete a course while raising a family and be
involved in active studies at the same time. Basically online
offering the best teaching quality and it is entirely possible
from the simplest of certificate to doctorate program.

assistants at office hours, or consult with other students in the
class

5. in order to study the questions, the instructor and the teaching
assistants will not distribute or discuss answers to any of the
questions by email. If you need help, please consider attending
office hours.
