Federal Unsubsidized Loan limit question for grad programs

Hi guys. Sorry but random question. My academic year and program runs from July 1, 2025 to June 30, 2026 on a quarterly basis. I've never applied for federal unsubsidized loans before. If I apply in my last quarter (starting April 2026), am I eligible to take the full $20,500 limit? Or would it be pro-rated to 1/4 quarter as 3 quarters have already passed?

And, 1 more add-on question. If I instead apply in July 1, 2026 when the new OBBB rules kick in, am I eligible to take the full $50,000 limit in my first quarter? (It's a health professional program, higher limit). Will it allow me to choose how much to take out? (July 2026 is also my final quarter fyi)
