Having an eight-year study gap may not necessarily disqualify you from pursuing a diploma in the UK. Admission decisions depend on various factors, including the institution's policies, your qualifications, and the specific program's requirements. Some universities and colleges may consider your prior experience and qualifications, while others may require you to demonstrate your readiness for academic study. It's advisable to contact the universities or colleges you're interested in to inquire about their specific admission criteria and whether they offer any pathway programs or options to help you bridge the study gap.
