Which College for 16yr old perusing BA degree

[sprout18]

My 16yr old has been taking classes through Sophia and ASU UL for the last year and a half. He has completed the following classes:

Sophia:
Approaches to Studying Religion
Art History I
Art History II
College Algebra
English Comp I
Environmental Science
Human Biology
Induction to Information Technology
Introduction to Psychology

US History I
US History II
Visual Communications
Public Speaking - completing now, will be done by end of December

ASU:
CIS 105 Computer Applications and Information Technology
SES 106: Habitable Worlds (4 credits - includes lab)
HST 102: Ancient & Medieval History - completing now, will be done next week
ECN 211: Principles of Macroeconomics - completing now, will be done next week

He's not really sure if he wants to do Business or IT. If its IT it will be more in aspects to business - he really liked the ASU CIS class which was basically taking spreadsheets and applying them to business. Ive looked at COSC a lot and was thinking that was the way he should go but I was wondering if there is a better or cheaper option for him. I can't figure out Excelsior since they don't really have straight transfer sheets for places like Sophia, Study.com, etc. So I haven't really looked at that one much. He really likes the self pace classes over the ASU set timeframe ones. He is so smart and doesn't really like being slowed down by not having all the information at one time. We are taking all the ASU classes because I know TESU and COSC both have RA requirements. Does COSC seem like the best option for him? Trying to figure out which way to go to decide on his next classes to take. Any help would be appreciated. Thanks.
