Saving time and money
I heard about Khan Academy from the testing center at the community college I enrolled in. I needed to take their math placement test in order to know which class I could take. Since my last college algebra class was in 1980, I knew I couldn't place out of the pre-req, but I was hoping to at least place in it, not below. For several weeks I watched videos and practiced with my 19 and 23 year old children. The test questions were completely covered by your site and in fact, I did place out of the pre-req- and the one class above! Not only did you save me the time of two math classes, but the cost of 6 credit hours as well! Thank you so much for this website!
Slow and steady, but straight A's all the way...
I have been attending community college for about 4 years now. It is not that I am a bad student - I am a straight A student, actually - it just took me a long time to figure out what I wanted to do with my life. I decided 9 weeks ago that I would major in Biology. I looked into the prerequisites and realized I was extremely far behind in math and chemistry. So much so that it would take me another 2 years after the end of this school year before I would be able to transfer to any high caliber universities ( I can't go anywhere else!). This was unacceptable to me. I refused to have to wait that long. I decided I would test out of many classes I could this semester, even if it meant teaching myself the material. So that's what I did. I ended up teaching myself Introductory Chemistry and Trigonometry (two subjects I was wholly unfamiliar with prior), successfully testing out of both! This is all while taking a regular full load of classes and maintaining A's in all of them. Now I only have to be at community college for one more year!
Now I have decided to get a head start on Calculus and you can bet I will be using Khan Academy whenever I get stuck! It has been an invaluable resource for me and my education. Thank you SOOOOO MUCH!!!!
Doubled my ACCUPLACER score
I'm 49 years old. I quit school in the ninth grade. I've done many jobs that have taken their toll on my body. At the end of the work day, I feel like l'm 85 yrs as a self-taught carpenter and handyman.
Recently, I decided to go back to school before I have to sign up for disability benefits from Social Security. Mastering elementary algebra is a prequalifcation for most technical vocations at the community college level. I've been polishing my algebra skills (and arithmetic) for 4 months and I doubled my initial score on the ACCUPLACER Exam using Khan Academy. I'm recently enrolled in a brand new technology program at a community college in Maine. I start the new program in the fall '13. I have some more work to do on the Khan Academy web site to attain mastery but, I would not be this successful in my academic pursuit if it weren't for Khan Academy. Thanks so much for your existance and methods used to teach me what I've learned in such a short time.
From Failure To Honor Student
After High School, I enrolled my son in college, full time. He decided to moved out and also to stop his education before finishing his first semester.
After 2 years of manual labor and unable to find a job anymore, he came back home. My first priority has always been education for my children so, when he told me he's stopped going to school, I dragged him, immediately, to the same community college to find out what to do next. School told me he was on probation, for failure to drop or continue his 4 classes.
I gave him an ultimatum, he either had to catch up or he is out. He went for the first option, he found the Khan Academy and studied Algebra for one month, he went to college for his test, he passed with an A and was ready for Trigonometry. After 2 and a half years, he just graduated as an honor student, with his Associate in Science and ready to go for his Bachelor in Computer Science. He watches every day this site, any subject he wants to.
I am a proud and thankful mom.
