there are several disadvantages of changing major halfway. in the first place, changing major halfway means that we spend much time, energy and money in the last major but do not mastered the whole knowledge of that major yet. second, changing major halfway needs a great resolution and we will face much pressure from others. finally, changing major halfway may increase the burden of our family finance in that we need to spend another amount of money on another major. in addition, if we change our major halfway, we will lose a chance to find out our potential. lack of persistence and willpower, we are difficult to be successful.
