You aren't being penalized -- you applied for a restricted license, which is exactly what you received.
It sounds like your license was suspended by DMV after a hearing for driving with a blood alcohol level over .08%.
For people over 21 who have no prior DUI convictions or suspensions, and who did not refuse a chemical test, there are two options:
1) A four-month "hard" suspension, with no driving at all.
2) Serving 30 days of complete suspension, then applying to DMV for a restricted license for the next five months.
Your restrictions are the standard terms.
I guess you could contact DMV and ask if you can return the restricted license and go without a license altogether until June, so you can get your full license back sooner... but I'm not sure about that because I always carefully explain the options to my clients, so I've never encountered the issue before.
This isn't a penalty, it's a reduction of the penalty. Allowing you to work and attend the school. At the end of the restriction you can get your license back.
