<p>Hi.
I'm considering to take some online courses that are at level of college studies.
I've gone through AP Physics/ Chemistry/ Biology,
so, I'd like to get some courses after that.</p>
<p>I've considered
Stanford EPGY
Coursera
and edX</p>
<p>but, EPGY seems too costy..
I'm not sure if I can get official acknowledgement from courses that are given in coursera or edX.</p>
<p>Thanks for your help in advance.</p>
<p>You can pay coursera for a certificate of completion (it’s how they make their money). However colleges are well aware that solutions to everything are available.</p>
<p>If you want to take courses at edx, coursera, or udacity do it for yourself and not for college admissions people that really don’t care.</p>
<p>EPGY is regarded much more highly as it is a real online course and not really categorized as a MOOC.</p>
