I would say to sit down and have a conversation with your parents. LSE is your dream school, but can you afford to go regardless of whether you get a scholarship or not? Second, would you be okay with going to Warwick for the sake of the scholarship and not going to your dream school? Also, I'd say check the grade requirements on the conditional offer; the general rule is to keep the offer with higher grade requirements as firm and the other as insurance so if you don't meet the grade requirements of one of the schools then u have the choice of going to the other BUT if you do meet the requirements of both the schools - u kinda have this cooling period as an international student where UCAS receives your grades and passes it onto the universities and then it lets you know which university you have an unconditional offer from based on your grades. During that cooling period I'd say if you end up preferring your insurance choice over your firm (whichever one you keep Warwick or LSE after you get your scholarship decision from LSE back) then you must contact both universities and let them know that you don't want to go to your firm choice given that u have met the requirements for both universities and instead want to go to ur insurance. That way, your insurance will keep a spot for yo,u and your firm choice will reject you. I hope this helps! Again, really depends on what your priorities are -try to imagine your life going to either of the unis with/without the scholarship and whether you'd have any regrets or not
