12. One of the labs in Bio 107 we offer in some semesters is a field trip to explore the native chaparral in Florida Canyon.

Am I Good Enough For Top Universities?


I’m currently a junior attending a public high school in the southern region of the U.S.
As of this year, I am currently the salutatorian of my class, however, there is a good chance that I could become the valedictorian by my senior year. My cumulative unweighted GPA is a 3.97; my weighted GPA would be a 4.32
My most recent ACT score is that of a 31, however, I will retake it until I make a 34 or 35.
I took 2 AP tests during my sophomore year and made a 3 and a 5. I am taking 7 AP tests this year.
I am the assistant principle to concertmaster in my school orchestra; I have auditioned and attained seats in a regional and state orchestra. I volunteer at my state’s art museum, volunteer at a food bank, and will tutor other students in the summer for social science courses. I will also be attending an accredited 4-week summer program with other juniors. When I was affiliated with a church, I volunteered during a week-long community outreach program in Pennsylvania. I wrote many articles and provided photographs for my school newspaper during my freshman year; I was made editor-in-chief of my schools newspaper during my sophomore year.
I have received e-mails from schools such as Princeton and Washington University in St. Louis. Would I be good enough for such schools? If not, what else could I do to improve my chances?

Is Backlink Quality Important?


It has not been a while since I started by business, and I am in a very niche industry so I have <5 competitors in my region. One of my competitors has somewhere between 3,000-4,000 backlinks. I know that because I googled: linkto:http://www.website.com
and this particular company is always on the top 3 search result on many keywords I search for.
I am gradually building my backlinks (around 400 now) using directory listings, press releases, technology articles, youtube.. and many other legitimate sources.
another competitor of mine doesnt even show on the google search results, but if I go to linkto:http://www.theirwebsite.com I get almost 1.2 million hits. My theory is, they used one of these backlink building services which created a lot of back-links but made them loose credibility with google.. is this in any way true? are those back-link building websites harmful?
Any other advise you can give?
Thanks
