Before you sign up for any course, get clear on the one skill you want to be able to do afterwards, because a course that does not move you toward a concrete ability is rarely worth the hours. Read the outline and look for specific outcomes and practical exercises rather than long lists of topics, since doing the work is what builds skill. Check how recent the material is, especially for fast-changing areas like social media, where advice from a few years ago can be misleading. Look for honest reviews that mention what the course did not cover, not just glowing praise, and be wary of promises that sound too good. Consider the real cost, which includes your time as well as the price, and compare it against free or cheaper alternatives that might teach the same basics. If a free guide and a few hours of practice would get you there, start with that and save paid courses for when you need structure, feedback, or depth you cannot find on your own. Choosing well early saves you from a shelf of unfinished courses later.
