Dear Student,
According to the rules you need to complete your one degree at first then you can move to the next one. It doesn't matter whether you have cleared the entrance exam or not.
As you are in 5th semester so you need to complete your course till 6th semester then only you will be eligible to take admission in DIED course.
And if you are going to take admission during your 5th semester then they will ask you for some certificate which you will get only when you will complete your current course like character certificate, transfer certificate, etc.
Good Luck :)
