Changing Psychology to Spanish A Level??

Hi, I’ve been in sixth form for about a week now I’m currently taking A level English Lit, Religious studies and Psychology but i’ve realised psychology is not for me. My sixth form allows subject changes and I am considering Spanish.. However in my old secondary school we took languages gcse’s in year 10 so i haven’t learnt the language for a year… i still know the basics but im not sure if that’s good enough, as in that im not fluent. Ps. I got a 7 in spanish (1 mark off a 8) If anyone that does spanish a level could help that would be great, or any recommendations for other subjects which i really only have politics to choose from.
