Computer Science A-level without Computer Science/IT GCSE

I have recently finished my gcses and i was wondering whether i made the right choice when picking computer science as one of my a levels, as i am completely new to the subject but i am quite interested by the subject. Will it be too difficult?

No harder than most A'levels. The course will be taught from the ground up, so you will be fine as long as you persist in yuor revision. One thing which is important to note is the NEA component (worth 20% of your final grade). You're going to have to do quite a bit of coding, to ensure that the project is of a suitable complexity for an A'level. If you don't know how to code, I would suggest learning over the summer, so you can hit the ground running come Sepetember.

Thank you very much for the feedback. I would like to ask what free online resources which I could possibly use to guide me for computer science A level.
