Struggling with second year architecture

I've began second year architecture and I'm finding it a bit difficult. I'd like to say I'm decent at drawing but I'm not too experienced in CAD and modelling, and this is where it's becoming overwhelming for me. I did good in first year and I could make nice card models, but now my tutors are expecting more sophisticated models via CAD which is expected, and as someone who has never used CAD as much, I'm having to learn it. I'm still navigating it and trying to learn it but I'm nervous and anxious that I won't master it or I wont have time to and that I don't have the intelligence or skills to understand how to create sophisticated models. A lot of people around me are decent at CAD and produce nice models which I think I could do, but it feels unachievable for me right now. I don't really have much confidence in myself. Its nearly mid November so I still have some time until my term 1 ends in late December, but I want to produce perfect and spectacular things but I'm battling with the process. I'm still trying to get used to second year and they did tell us that it would be a huge jump from first year. But I'm very nervous.
