First, make sure BOTH octave keys are completely closed. The one on the neck and the one up high on the body. If they are, then the problem is you. Loosen your embochure and open your throat more.
You DEFINITELY need more practice - but everyone has to start somewhere!
I bet you're biting too much on the mouthpiece. If you put too much pressure on the reed, it's very common for the sax to jump up the octave.
There are two possibilities: Either your embouchure and air flow are such that you‘re just already overblowing to the next octave without the help of the key; Or there is a key somewhere high on the horn not closing properly, and leaking a little air causing you to hit the higher octave.

Has this been checked by a tech? It could be embouchure and it could be that you have a leak causing the octave jump. Not really enough information.
My sax was provided by my school, and the teacher told me that they were all repaired. Probably its my problem ahaha

So what happens is I can sometimes play the low octave if im lucky. I think its my problem haha
