why students take college course ?

The short answer to this question is "probably." The well-designed programs that allow high school students to take college courses have features that support student success
Particularly for middle- and low-achieving students, merely offering the opportunity to enroll in college-level coursework is likely not enough to encourage post secondary matriculation and persistence. Instead, students need to be supported before and during their college coursework.

Inspiration is a great tool...but..like my favorite quote.."Motivation is What Gets You Started, Habit is What Keeps You Going". I strongly believe one of the most important things you need to do as college students is to setup these habits.

Setup habits that inspire and motivate you! Setup habits to succeed. That is one of the best things you can do for yourself right now. Make it a Habit to give it your best and to succeed .
College isn’t the place to go for ideas.The things taught in schools and colleges are not an education, but the means to an education.
