Around what time should should have start applying for college

Hi,
Excellent question, great job thinking ahead and planning for your future! I am impressed... :)
Different colleges have different admission deadlines and dates so I would check with the colleges you are interested in and also talk to a college counselor or the career center at your high school if you have one. The Fall is the start and deadline dates for most larger universities and colleges, also don't forget to apply for scholarships and financial aid early if you need it, at the beginning of your senior year. You will need to collect a lot of information from your parents for your financial aid applications.
Good luck! :)

Start applying during Junior and Senior Year. Collegeboard.org is a great resource for this! I poured through the pages of universities all over the U.S. when I was a senior in high school. Collegeboard was my go-to site! They put all of the information in one place and it is very easy to use. They even have various filters you can apply to see only colleges that have programs you are interested. To determine academic rigor, look at the admissions requirements, G.P.A. of past admitted applicants, SAT/ACT scores, class rank etc. This will give you an idea of what scores and grades you need to be accepted. However, don't be discouraged your application will be reviewed based on the full picture! College-board will help you get an idea of what is most important to the specific school you are applying to

Hi Zaire!
Way to think ahead and be prepared. You're off to a great start!
Most colleges and universities release their admissions application mid summer leading up to your senior year.
Now is a good time to make a list of the type of school you think you may like I.e. large, small, in a suburb, in the city, possible major, etc... and then look for schools you may be interested in. If possible try to visit the campus or go to their website to learn more about the school and their admissions criteria. Call the admissions office or go to the admissions page on their website and ask to have information sent to you and to also find out when the application will be available.
This is also a good time to search for scholarships that you may be eligible for. Make note of the requirements and the deadlines.
Best of luck Zaire!
