You'll be fine honestly. Even when things are tough and a pain in the arse and you don't feel like studying, just remember why you decided to do what you're doing. Maybe there is times you think "can I do it", believe me you can, anyone can if they put there heart into, which I am sure you're prepared to do.

The post I made about the laser locking is part of my thesis, in fact it was mostly taken from a chapter about locking. Bare in mind this is masters level, bit by bit it can be achieved.

If there's anything I can help with or advise you please contact me on discord or here, and i'll be happy to try and assist. For now have a lovely day and speak soon :)
