I need help
I need help with this course if anyone can help I would be very thankful.
That's a very open-ended request. You're more likely to get a useful response if you explain the difficulties that you are encountering, rather than making everyone guess which piece of advice might be useful to you.
As Knocksedan said, your question is very open-ended. What helped me a lot along the way however was this site called Memrise. You'll have to make an account, but it's free of charge and it's a great way to learn new vocabulary. There is even a Memrise course that teaches all the words from the Duolingo course and also explains some grammer. I'll paste the link down here:
Also, I'm certain that if you have a specific question, the community will be glad to help you with it. Good luck!
