Dr. Sanchita Ranjan,
The cluttered text means a lack of spacing. In the article, why don't you leave a one-line space where required? For example, you write Eligibility, and where it ends, keep a one-line space before the next part on the mode of selection, then again a one-line space if there is something following that.
Consider, too, the eligible qualifications. In case there is a huge list of optional qualifications, instead of simply writing them in one long sentence with the 'or' everywhere, why not put it this way- mention the first one or two qualifications required, then just write "You can check out the official notification to know the other optional acceptable qualifications". Immediately after that, you could leave a one-line space again, and then write "Additionally, you must have a valid GATE score/GPAT/NET (and whatever other options are given - here you can mention all those since those are few in number).
What happens when relevant spacing is not given is that the reader will simply skim over the content and/or not bother to go through anything at all and just leave the page and the site. The reader may think "It's very confusing, let me go to the official website only". See, the point is to keep the reader on the page and, with internal links, within the site for a tad longer.
A further point about spacing - I suggest that you start the first sentence of a paragraph right after the closing of the h2 or h3 tag. In this case, a big space is not required and it will look neat.
Edit your article and make these basic changes and then you will see for yourself how much better it looks. If you require further guidance, let me know.
