Ah, excellent; well done for replying so clearly. It sounds as if you're on the same track as all of us, when starting out. Obviously you should address these concerns with your tutor; he/she will have doubtless heard much the same from many pupils. Meanwhile, if you're not doing it already, I'd recommend playing for short periods, as often as you can, but regularly. Two 15-minutes sessions, each and every day, no exceptions or excuses, will cement the 'information' very quickly. Far better than an hour once a week. I will assume that you have exercises, routines, to practise, from your tutor..? Do these, religiously, in your practise sessions, plus any other stuff you want to do from other sources (method books, U-tube etc...), but avoid playing for too long at a time, especially for the first few months, as this can seal in bad habits and damage your hands. Depending on the complexity, it's normal to have to refer back to the partition (be it tab, notation or chords charts... whatever...) at first, but much will become 'ingrained' over time, as long as you keep plugging away at it assiduously. There is no 'silver bullet', but be assured that every guitarist, whatever their talent, started out with your level of competence. It's only the practising that makes the difference, and it's not overnight. Speak to your tutor, then, follow their advice and method, and trust me; it will all come together, and all the faster for being patient and doing things slowly. I'll end with my usual tongue-in-cheek encouragement ...
It's the first forty years that are the hardest, after which things sometimes tend to get very slightly easier.
