what do you think is the best way to approach a good practice session? like what i mean is, what is the most efficent way to practice ur music that ur given from ur teacher? my teacher usually gives me 3 songs a week. is it best to learn 1 song completly and then move onto the next and so forth? or is it better to just pick up any of the 3 songs and practice one song for a little bit, then go on and practice another?

It's good to keep up on everything all the time. Getting in a bit of each thing in a practise session is always a good idea. You can focus more on 1 thing if you think it needs more work, but try to make sure you hit up all your other stuff too even just for a few minutes.

I would do a little bit of each one every day. Maybe a bit more on the one you are having most difficult with. Balance is best.

I find that new music should be practiced every day. Music that has already been learned but still needs work is next on my priority list. Things that have been memorized and performed don't need constant attention unless a performance is coming up.

Funny. I say the opposite (to the younger ones anyway) lol. I don't know how far you are into your lessons or how old you are but here's what I tell my students.

I tell the young kids and beginners that it's like their spelling and vocab words. Spell one over, over and over until you get it, then move on to the next one. That's how I have them do it at lessons too. We will work on a sentence a few times before we move on to the next one. I don't want to send them home having only gone over things once or twice. I think it's important that they understand that the more difficult sections need to be practiced more than the easier sections.

If they have been taking lessons for awhile, and know how to practice at home I encourage them to find a method that works best for them. Some people burn out on the redundancy of repeating one piece or section, while others want to master it before moving on.
HTH!
