What camera and Lens?

Hi there. Complete beginner just enrolled on photography course. I need to buy a camera and Lens. I've looked at lots of reviews, comparisons etc and I think for my price range (~1.5k) I would like to buy the Canon EOS R7 Mirrorless Camera with RF-S 18-150mm F3.5-6.3 IS STM Lens. From what I have gathered this is a high spec entry level camera at the top end of the beginners/budget area with a fairly average all rounder lens. I want to shoot both landscape and wildlife, which I believe for the best shots would require two completely different types of lens. I don't want to buy two lenses at this stage and would rather just practice with one. Would you recommend sticking with the lens in this package or going for a more expensive lens? Thanks in advance!
