In fact, studies find that most students change majors at least once and many switch several times. So it might not be a good idea to pick a college only for its program in one major. Instead, consider colleges that offer a range of options that interest you. That way, changing majors won't necessarily require changing colleges, too.If I want to become a doctor or lawyer, do I have to major in premed or prelaw? It might surprise you to know that majoring in premed or prelaw is impossible at almost every college. Premed and prelaw, are not majors. They are special college programs that guide students through the process of preparing for and applying to professional schools, such as medical or law school.So, if you choose to participate in one of these programs, you'll still have to declare a major. Many premed students, for example, major in biology or chemistry. However, as long as you fulfill the admission requirements of the professional school, you can major in just about anything. In fact, professional schools often look for well-rounded students with diverse backgrounds.See the full list at2. Word attack （教师可补充词语的其他常用意思，辅以例句。

Background informationTips for Choosing Student Clubs and OrganizationsFreshmen play a big role in the life of college organizations. You comprise the new generation of recruits, the ones that will potentially take on the responsibilities that the seniors and juniors will leave behind. Freshman recruitment is the lifeblood of college organizations. The more recruits they have among the freshmen, the longer the club can exist.•Choose One or Two Potential Clubs to JoinNarrow down your options to five or less and then choose one that you intend to join, and another that you could join if you have extra time to spare. Better yet, join one club and wait a year befor e joining another. Because you’re still adjusting to college life, you may have less time to spare for extracurricular activities than you think. If you join too many, you may have to give up your weekends or shave a few hours off your study time to attend meetings. You’ll burn yourself out faster if you have too much on your plate on your first year. •Consider Your Skills and InterestsSkill-based clubs like the music or drama club may require an audition. Many college clubs related with the performing arts take their craft seriously. After all, if your major is related in any way to music or theater, being in this group can get you started in your chosen career. Plus, joining and being an active memberwould look great on your resume. Your future employers would always look at your list of extracurricular out of genuine curiosity and because they want to know how well-rounded you are. Joining clubs can be great for student athletes hoping to go pro someday. You can practice your skills off-season and you have a better chance of being scouted because of the exposure that the practice games afford.2.
