1. Visiting your school office to pick up your transcript yourself: You can always walk up to your school office, especially if you need it urgently, and ask for your transcript. This is most likely one of the fastest ways to obtain one. You will firstly be given an unofficial version, while the official one might take some days to process.
2. Make a request through your school website: You can also visit your school website to request for your transcript, maybe you are distanced from the school location. Actually, this might not be available for all schools, but you can ask about yours.
3. The use of a third-party site: You can use a third party sire like "Need My Transcript" and "Parchment" if you are still a current student. You can use this site to outsource your transcript, provided you are still in school, probably at or close to the final year stage.
