Unless things have drastically changed at OCS, you have no access to personal electronic devices until your last three weeks, so no.
When I went through API, students were not allowed to use electronic devices in the API building. Not sure how that's changed in the last couple of years with CNATRA issuing everyone iPads. When you get to the VTs/HTs big boy/girl rules apply, but don't expect to be able to continue that practice when you get to the RAG, since a lot of info will be classified depending on which platform you fly.
