Can I get an Aircraft Maintenance License through passing SOL exams?

Unfortunately not (but this is not the purpose of PART 66 online with SOL) The purpose of SOL is to help you prepare for your formal license exam. If you understand how Part 66 works you will know that exams are taken under exam conditions, with an examiner present, to make sure that you are the person who you say you are (by showing Passport etc.) plus to check that you have no other material with you during the examination.
