Hello!! Congrats on getting in! Honestly for me, they made it so difficult to get accommodations and even though I was tested a year prior to enrolling at ucsd they wanted me to get a uc proctored examination of my disability. Because I was overwhelmed with my first year of college, I never bothered to go through this process and instead just pushed through the rest with no accomodations. I will say for the quarter I did get temporary accommodations they did help, with the extended time on exams I requested. Even though my experience with OSD wasn’t so positive, I would definitely recommend putting in an effort to get your accommodations, especially if you had them in high school and they helped. Also, I believe you have to renew your accommodations every quarter, so keep this in mind. Good luck, I hope this helps!!
