Is computer science at Nirma University a good option?

Whether Nirma University will be a good option or not depends on what other options you have.

If you are not getting admission at DAIICT (at ICT with CS) or SVNIT, particularly if you are from Gujarat, then you can certainly go for Nirma. These colleges are a tier above Nirma. DAIICT offers an average package of around 12 LPA.

However, Nirma University also offers a decent CSE program. Here is a brief overview of the CSE program offered by the institute.

So, there are better options than Nirma for a CSE course, however, if you are not getting admission at these institutes, Nirma will be a good alternative.
