I cannot recommend the MBTI for this purpose, it really doesn't have good theoretical underpinnings OR predictive validity. Despite it's popularity it is really a rather shoddy piece of work. The first online test that comes to mind that has both of those attributes is the
IPIP-NEO. However, I suspect that even this well-regarded instrument will not tell you what you want to know.
In part, this is because this personality survey isn't designed to, and also does not claim to, give you the perfect career for you. There are lots of people who claim to do precisely this, but you should be suspicious, because they are in the business of selling books and seminars. I've read lots of these books, and sometimes there are useful insights in them, but in general they are not capable of answering your question.
Reading this post, and
another one in the Academic Guidance section, it seems to me that you are uncertain about your future, and you want to be pick a course of study with a reasonable chance of success. This is something worth thinking about, and worth gathering information to try to make the best decision. My caution for you is this kind of prediction is an imperfect art. Art, not science. There is lots of judgment required, which mostly comes from experience. The results of a personality survey can be a useful input to this kind of decision-making process, but cannot give you a definitive answer of the form: The best job for you is _______.
The best results would likely come from talking with a very experienced person in a field you find interesting, who also knows you well. In lieu of that, you can find many, many interesting people on this forum, who have written at length about what their jobs are like, and what makes their jobs interesting to them, and what skills have served them well. You might be able to find something that piques your interest in this way, and then you might also be able to formulate a more specific question.
