The most common mistake when choosing a course is starting from the course title rather than from the gap you want to close. Before comparing programmes, write in one line what you will be able to do after the training that you could not do before.
Second question: is the content practical or theoretical? Ask for the programme outline and look at the ratio of exercises and projects to lectures. A programme that does not end in a tangible output rarely changes anything in your performance.
The third question is about the trainer: do they practise what they teach today? A practising trainer brings examples from last week, not from a book published ten years ago.
The fourth is the most neglected: can you commit? An intensive eight-week evening programme needs time for exercises between sessions. Choose a schedule you can actually keep — dropping out halfway is worse than postponing to the next intake.
Finally, ask about the certificate: on what basis is it awarded? A certificate given for attendance alone says nothing about you; one awarded after a practical assessment is evidence of real capability.
