I looked up for the exam date and it says 9th April which is just few days away. According to that information, the applications have long since closed and probably admit cards must have been provided to candidates by now.
However, because of lack of information availiable on internet, I contacted the university directly and they responded back by saying that last date isn't confirmed and the applications will be availiable till June. If what the administration supplied is true then you have time till june to register. Otherwise, you are too late to apply now.
I hope this helps.
The last date of registration for IUET is 15th April 2019. So you better hurry.
