I went to UCLA as an undergrad, majoring in a field not related to Speech Language Pathology (Global Studies). I'm currently a graduate student in TESL (Teaching English as a Second Language) which is more closely related to SLP as I am considering linking it to accent reduction, in which I have some experience teaching. In addition to my educational background, after graduating from UCLA, I taught ESL (English as a Second Language) for approximately 3 years in a variety of private ESL schools and last year (2013), I spent the fall semester in Japan where I participated in a study abroad program, learning Japanese and also teaching English at a university. Moreover, although not fluent, I speak intermediate-level Japanese, which I learned in high school, in college and also utilized while I was living in Japan. My GPA as an undergrad was not stellar, and in grad school it is currently only 3.28 (while studying Teaching English as a Second Language). However, I am shooting for straight A's in all of my preliminary SLP classes. I have a lot of leadership and multicultural experience from when I was an undergraduate student (I was a leader in the student government and was also an exchange student with Rotary International in Japan several years ago). Around the same period of time, I received a variety of scholarships from my community college before transfering to UCLA. My quantitative skills are not that great, but I'm hoping to improve them before taking the GRE. I'm not too worried about my verbal or writing skills. Lastly, I recently started out as a volunteer for a book club for individuals with Aphasia and will be continuing that for about 3 months. How can I improve my chances?? I realize that my grades need a LOT of work. Any other suggestions or advice will be greatly appreciated!
