mocks dropping

hey guys! js wanted to ask ab mocks cuz im feeljng a little disheartened rn, i started ucat prep like 5 days ago and since then ive done 3 mocks. my first was 1740 b2, then 1800 b2, and now today i got 1660 b2. idk how i legit thougbt it was going well too 😭 is this like normal to have a bad mock? and tbh it was vr that screwed me over, other sections were pretty consistent. any advice is greatly accepted 🤗
