Interest in study is very important because it keeps students motivated. When students like a subject, they understand and remember it better. For example, I always did better in subjects I was interested in.

Interest is not always necessary. Sometimes, hard work and discipline can make up for a lack of interest. For example, I didn't like math at first, but I started to appreciate it as I learned more about its uses.

Interest in study depends on the subject. For creative subjects like literature, interest is crucial. But for technical subjects like math, understanding the basics is more important. I found history fascinating, which made it easier to study, but I had to work hard in chemistry even without much interest.
