Hi

This is a bit difficult to predict that with 168 marks you will get a seat in mnit  allahabad or not as cut off  keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the jee main examination , number of seats available for the branch you want etc.

With 168 marks, your sc category rank is expected to be around 130 while your general rank is expected to be around 5336 - 6986, for this you can refer to our page link is provided below

When we go through previous year trend then ,
In round 6 of josaa counselling 2020 , for sc category  to get computer science engineering   , 932   was sc closing rank  under home state state quota in mnit allahabad

You can check the same at

So, with 168 marks i. e around 130 expected SC category rank you have very good chances to get it a seat in MNIT Allahabad

Now,
