There is no fixed limit on the number of attempts for SSC CGL. You can appear for the exam as many times as you want, but you must stay within the age limit criteria. For most general category students, the age limit is between 18 to 32 years. However, it varies depending on the post and reservation categories (SC/ST/OBC etc. get age relaxations). So technically, if you stay within the allowed age range, you can try multiple times. That’s why many students appear for the exam every year until they get selected in their preferred post or department.
