really tensed about my slat results

got 42 which is 95%tile, but according to my math im probably ranked 700-800, which means I'm fcked cause I only registered for ba llb, my stupid ass forgot to register for bba
I spent 2x efforts on slat because I was depressed as fck after clat, I cant watch all my efforts go down the drain because of my stupidity
why do you need to apply for programs separately in slat, why cant I choose it while admissions!!!
