Day 5 - Squeaking Issues!

Hello again!
Sorry I didn't make get another post published yesterday, I was so busy with my ISP projects (practising Sonatina/exam pieces & designing the CD cover, as well as my Spanish ISP). But I'm back! Yesterday was a good practice day - I have officially perfected Hornpipe from Water Music (the ending sometimes is a little off, however) and the Minuet, as well as the scales (as long as there is no low C natural!), and of course Sonatina is coming right along.
The only problem is today I was HORRIBLE! I kept squeaking and squawking ALL THE TIME! I hope I was just having an off day, because I feel that today, as far as Sonatina goes, I am almost back where I started (I messed up on easy notes too!)!!!
I am probably stressing myself out, and this is just "One of Those Days" but I think tomorrow I will ask to practise together with our sections. Oh wait, you won't see this post until after our projects are finished. I better write myself a reminder to ask!
On the plus side my timing is fairly good now, and I can play the correct tempo (in correlation with the piano track anyways). The one area where I may have to work on tempo still is bars 36, 37 and 38 (the last 3, for clarification). I'm pretty sure I'm not playing the sixteenth notes quick enough. Today I also attempted to find an audio recording of my part, just to hear what it sounds like, but no luck. I suppose this Sonatina was not one of Mozart's more popular ones.
Hopefully tomorrow goes better than today, and that the exam and recording the track go better (I haven't really recorded yet, because our microphone doesn't pick up sound very well. I couldn't really hear myself at all). I'm crossing my fingers, and also practising Sonatina lots!!
