College is very different than high school; once you arrive on campus, you will need to learn to be your own advocate. Don’t be intimidated--you’re going to develop an incredibly valuable skill!
While many schools offer support to students with learning disabilities, you will only receive a service if you specifically request it. Before you arrive on campus, work with your parents, high school teachers, and counselors (and, if necessary, health professionals like doctors and psychiatrists) to assess your learning style and needs. It will be helpful to know how you learn best and strategies that help you succeed. You should also be aware of the circumstances in which you do not learn well. You will also need documentation of any official diagnosis.
One note: Different schools offer different levels of learning disability services, from basic accommodations all the way up to extensive programs run by several staff members. Ask before you apply! Our book The K&W Guide To Colleges for Students With Learning Differences is a great resource for services, admissions, and support at 350 schools.
Many students believe that because they have to ask for services, their colleges don't actually want to provide them. This is not true. Your college admitted you, and they want you to succeed.
You will need to be more upfront and self–sufficient than you were in high school. But if you stand up for yourself and communicate clearly, you're likely to get all the support you need.
