Thoughts on Lnat-practice website?

I've been practicing using the lnat-practice website (https://lnat-practice.com) for over a week now. Like 10 days ago I took a practice mock on the official lnat website to see my baseline and I got 21/42.

Today I took a mock exam on the lnat-practice website and got 40/42. Now, I know this is definetly unrealistic and the questions must've just been easy (though they did have 4 answer options instead of the 5 in the official lnat simulator so that prob pushed my score up) but, how unrealistic do you guys think the website is?

Does anyone else find that the website's questions are wayy easier than the actual exam?

Also, does anyone have recommendations of websites/ other resources that actually correlate with the difficulty of the real LNAT?
