Lcat for Lums

I’m giving lcat in March for Lums. My SAT got cancelled/postponed 3 times due to god damn corona and I was worried that my March SAT might get cancelled as well. And as far as I know my application will not be eligible without SAT that’s why I opted for lcat. But the last lcat was conducted in 2015 and there is close to none information available online. Therefore I was wondering if anyone else is also giving Lcat and can share information with me. My main worry is negative marking and use of calculator.
