In your opinion, how important are entrepreneurship courses in preparing young entrepreneur to enter the market?

If one wants to get into business and currently he/she does not have the experience and knowledge in the business, it is highly recommended for him/her to attend entrepreneurship courses or other related business courses.

It is difficult to do thing if we do not have the knowledge how to do it. Entrepreneurship courses prepare one to get to the business and he/she will know the business environment.

Entrepreneurship courses will be extra-ordinary in preparing a young entrepreneur enter a market. This will be able to shape one's natural entrepreneurial skills into workable business models to successfully drive innovation and be conscious of possible turbulences and prepare in advance.

it is very necessary for entrepreneur to widen his knowledge area which let him to formulte his strategies and required actions for each sitauation  

What I strongly suggest is to be very open-minded with the various experiences that you come across in life, college and business. Everything before becoming an entrepreneur is background information and a series of practice tests that prepare you for your business venture. Sure, you'll make quite a few mistakes when you launch your first, second, third companies and so on, but now is really the time when you need to focus on exposing yourself to as many different types of experiences as possible. Think of your head like a sponge and try to fill it up with as much stuff as possible.

The importance is to pump new blood into the veins of entrepreneurship, which helps to develop this area

I think entrepreneurship courses can useful for young entrepreneurs; however, they are not the only way to learn business skills. There are lots of books out there that shed light on both the sucesses and failures of doing business. It's important to learn about what has and has not worked in the past so that you do not repeat the same mistakes.
