As there is no restrictions to do 2 courses together but the only condition is you cannot go for two degree programs at one time but yes, you can do 1 degree and other diploma/certification course at the same time as this is valid. But as per my view, it would be better if you focus on 1 field as more number of options will make your confused so better to go for one in which you have maximum interest and potential but rest depends on you.

Good Luck!!!!
