Yes. You can study online for any and all licenses that are required to become a Financial Advisor.
There is much less education than most people imagine necessary to become a FA (Financial Advisor)...a degree in Finance or related field of study is NOT necessary. (Common misconception) Passing a Series 7 test (avg 30-33% failure rate) is the main criteria...and typically, depending on your state laws, a couple other "easier" tests. Essentially, unless you pursue "extra" education you will simply be exchanging one sales job for another.
Please pursue additional education and knowledge to better help your clients through every venue possible. I suggest "The American College" (available online) which is the originating source of the CFP designation along with many other "valid" credentials recognized by EVERY financial institution. Keep in mind that you must NOW have a Bachelor's Degree in "any" field in order to finally receive the CFP designation...if you haven't finished one yet...you can take the CFP courses while also completing your degree.
There are also "training" programs available through various firms...but they are essentially "sales training" programs and the educational aspects end where the "studying for the licenses you need" ends.
F.Y.I....I also made the career change around 26 years of age...and love what I do...but then again, I watch FOMC meetings in reruns for the "kicks and giggles" entertainment value of them....they truly are fascinating if you understand the intracacies of what is being discussed.
Series 7 study materials "most used" by Wall Street firms (like the one I started with) are available at:
