Doing any sort of study can be time consuming and so it could be a good idea to have enough time to concentrate on it fully. However, it can also be expensive to get qualifications and if you are paying for a course and not earning money, you could find financially you struggle. Therefore, it can be difficult to know whether to study for a marketing diploma when working or not.
Advantages The main advantage of studying and working at the same time is the cost. You may be lucky enough that your employer will fund your course and this will mean that you do not have to pay. They will expect you to study in your own time and continue to work though. If they do not fund it, then again, you will need to study in your own time but you will also need to pay for it. By working, you will not only get money to cover the course fees but also your living expenses.
Having some work experience will also look good on your resume. Even if the work that you are doing is not related to what you would like to do in the future, it can be still show that you have some experience. If it is within the right industry that can be even more helpful, even if it is not doing the same sort of role that you would like to do.
Disadvantages If you work at the same time as study, you will have a lot more distractions. You will have the pressure of work plus any work that you bring home with you to do as well as the study. It can take up a lot of time and you may have to see friends and family a lot less and will not have so much relaxation time.
If you find that you do not do as well as you had hoped because you could not put in the required amount of time to study you could regret working at the same time. This could depend on the nature of your job and how much free time you normally get. It could also depend on how self-disciplined you are with making sure you find the time to study.
So whether you find that study and work together pays off could very much depend on you and your job. The course may need a lot of time that you do not have to give it, or you may be self-disciplined enough to manage your time well. You will need to consider your job, the course and your personality when deciding whether you should study for a marketing diploma while you are working. If you work long hours and you need to study a lot, then it may not work. However, if you only have a part-time job, then it may be easier to fit it in, but it does depend on your other commitments.
