The three main parts of a CV that you should update first are: Education: Make sure that the education section of your CV is current and accurate, including any degrees or certifications you have earned since your last update. Work experience: Update your work experience section to include any new jobs or promotions you have had, and make sure the information is relevant to the job you are applying for. Skills: Make sure to include any new skills you have acquired, and highlight those that are most relevant to the job you are applying for. It’s also important to update your contact information, and consider adding a professional summary or objective statement that highlights your qualifications and career goals.
