A study partner can completely change the way you look at your academic life. He/she can make studying more enjoyable so that both of you can study for hours and hours without ever feeling tired. However, finding such a reliable study partner is not easy; you’ll fail a number of times before finding the right one.
A study partner from the same class would be the best, but that is not a necessary. Your study partner can be from a different class and can be junior or senior to you. A senior partner will be quite useful; especially if he can take the time out to solve your academic problems. He can help you in writing the best essay because he would have written similar essays sometimes back. On the other hand, a junior study partner will be respectful to you and you can ask him small household favors in return if you help him with the academics.
A study partner from the same class would be good, but can invade your privacy. Especially when you are taking external academic help, it may not be the best to have a study partner from the same class. He can leak out your confidential details and can completely ruin your reputation in the college.
