What extracurricular activities and how many do i need to get into ivy?

It's more about what's impressive.

If you're on the science, spirit, math, etc. clubs and have more trivial positions, it won't do much for you.

But, if you found the science club, start a 5013c non-profit outside of school to help orphans in Cambodia, do upper-level research with a local doctor, etc., it's more likely to help.

Personally, I was involved in many clubs and committees in high school, but very few of them were helpful for college applications.

Basically think of it like this: most people who are applying to the top schools are clones of you, if not better/more competative credendentials than you. Plenty of people with 4.0's, insane leadership, etc. get denied, while some matheletes, basketball players, or other club leaders/founders get in. Most people applying are exceptional students, far above average, and getting in is essentially a mere gamble. Two people might have identical qualifications-- one might get in, the other might not-- or neither of them might get in. A number of other factors come into play. It's kind of a crap shot, so apply to at least a handful of 'safe' schools that you know you can get in.

And, don't go to a college if you don't get a full scholarship-- or near it. Graduating from a top school with $100,000 sucks and isn't worth it for a mere bachelors degree. If you get a full (or near full) scholarship at a state school, seriously consider it. Graduate debt-free with money in the bank and start a company. Or attend a top graduate school. If you get a full scholarship at a top school, obviously consider going there instead. At the end of the day, it's just a bachelors. Most career fields, at the upper level, need at least a masters if not a doctorate. Spend as little (of your) money as possible on education.

With that said, good luck.. and don't worry about a bachelors degree too much. You've got plenty of education to do after that. :)

yeah i agree with what the above said that it's the quality of the works that counts. The best extracurricular activities I could think of are doing volunteering works at community centre to help people (recreation centre, red cross or hospital), joining the student clubs, playing sports etc. It'll be very impressive if you have many experiences connecting to the society outside of school.

it's not quantity but the quality of your services that counts. you could only do one extracurricular activity, but be extremely and exceptionally good at it.
