I'm sure many of us here have'nt checked their admission status, reason being that we don't know the exact site, while some other blogs refer us to my.unizik.edu.ng which is the wrong website for 2016 batch, that site was only valid in 2015, so here's the steps to check admission status, you only need your Jamb Reg No.
1. Now visit portal.unizik.edu.ng, remember that site you applied for post UTME
2. Input your reg no at the first space and allow it to load, do the same with the second space and click login
3. Click on the first symbol, which is green, it almost looks like all these chinese languages.
4. Click at the 4th option which is admission status.
5. Click check admission status

that's all, good luck.
