Hi there,
Reaching out to a tutor is definitely a great option.
Of course you can brain storm your ideas or right down random thoughts whenerver they might occur (exersiece really helped me come up with arguments for my dissertation for some reason).
Thankfully, you still have over a month until you reach your deadlines, and at the moment 4K or 7K words may feel like a lot but believe me once you'll be writing about something you're very interested in, it will only be a matter of days for you to complete your assignments.
Perhaps you can reach out to previous uni students who completed your course? They will definitely share useful tips which helped them complete all coursework.
Additionally, don't be afraid to reach out to your fellow coursemates as they might be struggling as well. Maybe you can brain storm ideas together? Or create group study sessions to motivate eachother?
Finally, if you still need help, keep reaching out to your tutors. They are here to help you and give you feedback so make sure to take advantage of that.
I hope I managed to help!
Best of luck,
Melanie
