Im a freshman and i have a a 2.7 gpa do you think i can boost my gpa up to 4.0 + by senior yr .?

-I just got my scedule for sophmore yr . and my counselor gave me two honors classes !Yeah you can do it! Just push through, pay attention, sleep well, eat nutrient rich foods, and be physically active. These factors all contribute to a better more focused you which means you can up your grades. I too am also going on to my Sophomore Year! I took honors everything. :D Make sure you reread things or look over notes on subjects you don't understand. GOOD LUCK!If you have a weighted system in you school, yes it is possible. A weighted system meaning you get a higher grade if the class is an honors class. You would have to take quite a few honors classes and make sure you got an A in every class. If you do that i believe it is possible. But make sure you school do have weighted system.
The only way to have a 4.0 (perfect GPA) would be to always get A's. Since you have a low B GPA right now, I'm not sure if you can get a 4.0, as the grades you already have might have knocked you off the mark. You still do have a chance of getting around a 3.5 though, granted you get mostly A's from now on, so just keep up your grades and you should be fine. In my opinion, anything over a 2.5 is "acceptable" and anything over a 3.5 is doing really well. :)
You have plenty of time to get your GPA up there, just keep working hard, try your best and you have 3 years to raise it, so you'll be fine, good job on the honors classes! try hard in those especially!
