Can I prepare in 1 month for a B.Ed entrance exam at DU?

The requirements for B.Ed admission to DU are as follows:

Written Exam:

If you work smartly and analyze the pattern of questions asked in previous examinations, devote a focused time period to preparation, followed by sufficient practice tests, you can certainly clear in one month. 

If you are well-versed in your subject matter, there is very little required for you to do. Hard work comes after good fortune. So, first and foremost, your planning should be smart, and then, you must work and prepare well beyond the planned strategy. Each of us has our own set of self-beliefs and abilities. Thus, you do not have to compare yourself with any other person. Just believe in yourself and go ahead. 

Interview: 

During the interview, a panel of teachers/interviewers/professors will fire off all sorts of questions at you, including subject questions, psychology questions, general knowledge questions, confidence check questions, and, most importantly, your honesty, which is one of the most important aspects of being a good teacher. A good strategy, a lot of planning, focused work, confidence as well as a strong belief in yourself, are required.
