No, I don't think you can or the use of doing it that way. When you are doing a degree course, you technically have to spend a lot of time for it's studies. In Hotel Management, it is of prime importance to be there in the class and attend your practical. Soon after you finish your Diploma, you would have to do industrial training for about 4 months. And, if both your IT and your degree classes clashes, then you are going to loose both. But, if you really want to study something extra, then I would suggest you apply for some online certificate courses. For now concentrate on your degree.
