You can apply online through MP UG counselling and put Holkar Science College as your first preference, with your preferred subject combination. 

If you pass the cutoff then the following process will be easy but if you cannot make the cut off and want to join Holkar then wait for the publication of the second and third lists. 

Most of the students panic when they are unable to get in the first round. But there are many students who later do not get admission there, this makes space for other students belonging in the 2nd and 3rd lists. 

So, it does not matter from what list you get admission, as long as you can be a part of Holkar. There are more than three rounds so try waiting, as it will create some vacancies.
