i can say the placements are average . the placements vary year to year so cannot predict which year's placements would be good .the placement for other courses like b.tech is good so the placement wing works hard in getting companies. you not need to worry since you are from bihar ,there will be students from up and bihar and you will not be alone .however knowing a little english will help you . https://www.careers360.com/university/mizoram-university-aizawl
