As mentioned previously - why on earth is your instructor teaching you about the use of NAVAIDS before your first solo?!
If you're at an airfield that requires it, a transponder is the only bit of 'kit' you need.
Carb heat is often forgotten - but a useful tip as mentioned above is to push it in at the end of the downwind (pre-landing) checks.
I hope it all goes well - but concentrate on the radio and leave the NAVAIDs alone!
