Know your major scales! They contextualize the notes, making each note much easier to find. The examples you provided, for instance, are both in the key of C, so if you know how to play a C Major scale, you can see that most of the notes fit within that scale. So you can find certain anchor notes within the scale and figure out the rest from there. Often, you don't end up having to find each note on its own, but instead you find them as parts of scale fragments.
In other words: In study Number 1, you're in C Major and you don't get to an accidental until the last note of measure 7. So start by finding the first note, which is a C---that's your anchor (I might also choose the G above C as another anchor). From there, you see that you go down one note in the scale and then a third. Repeat. Measure 3 is a scale fragment---start on the anchor C and simply go up the scale for three notes, and then go up a third to the anchor G. From there, walk down the scale, etc. etc. Notice that you don't actually have to know where the B, D, E, or F are on their own, you just have to know how to play a C Major scale; that's the whole point. When you get to an accidental, you play the note from the scale but adjusted up or down based on whether its sharp or flat---in this case, its especially easy because it's the note right below the anchor G.
This approach to reading works in any key, and musical notation really encourages it: once you know the key of the piece, every note that doesn't have an accidental is within the scale, and the accidentals are like red flags saying "Heads-up! This note is outside the scale!" The point is, if you know your major scales really well (which you should be working on every day anyway), you can take advantage of that knowledge to offload the mental processing of trying to figure out where each individual note is. Instead, you see how the notes fit together, and the piece becomes both easier to play and also makes more musical sense.
