Transferring to Academic Account

I want to change my account to academic one. When I first create this account, I don’t know what is the difference between academic and corporate, and I choose the corporate one. Now I need the academic account. But I cannot find any button that could simply “apply for academic account”. And when I go to the Pricing page and click on “Apply now”, it directed me to my home page, and I did not know what to do next. Could you please help me with it? Thanks!
