* Type of degree: A Master's degree typically takes 1-2 years, while a Doctorate (Ph.D., Ed.D., etc.) can take 4-7 years or even longer. A second Bachelor's degree will generally take the same amount of time as a first (4 years).
* Prior education: If some of your previous coursework can transfer as credit, it might shorten the time needed for your second degree.
* Course load: Taking a full-time versus part-time course load significantly impacts the time to completion. Part-time study often extends the duration considerably.
* Program requirements: Some programs are more intensive and require more time commitment than others.
* Institution: Different universities and colleges have varying program structures and pace.
In short, there's no single answer. It could range from 1 year to 7+ years, depending on the factors listed above.
