AUSTIN, Texas (AP) _ Gov. Ann Richards on Tuesday gave Texas lawmakers ''an A-plus'' and high marks to herself, despite leaving next year's budget and its projected $5 billion deficit until a July special session.

''All in all for me, it has been a fantastic session,'' said Richards. ''And I think it's been a good one for the people of Texas.''

Legislators worked until the midnight Monday deadline of their 1991 session, passing an ethics bill in the final minutes. They also overhauled the public school finance system for the second time in 12 months.

Having no budget to write left the session with plenty of time to consider many other ideas - most of which failed.

Debated but killed were bills to: allow Texans to carry concealed handguns, allow speeders to get off with $5 coupons, repeal the ''LBJ Law'' that lets Texas U.S. senators seek re-election and national office simultaneously, and promote so-called ''potty parity'' to provide more women's restrooms in public arenas.

Senators did pass a ''potty parity'' bill in April requiring that women's restrooms outnumber men's 2-to-1 in new and renovated buildings such as football stadiums and amusement parks. The House amended it to set the ratio at 3-to-2, and a conference committee failed to negotiate a final compromise.

The ethics bill is supposed to increase public disclosure of lobbyist's expenditures, and close a loophole in the state bribery statute that critics have said allowed politicians to disguise bribes as campaign contributions.

It follows years of reports of lavish spending on lawmakers by lobbyists and comes amid a grand jury investigation of influence-peddling at the Capitol.

Voters will get their say on the plan Nov. 5 in the form of a proposed constitutional amendment establishing an ethics commission, which would have power to enforce the new law and recommend how much legislators should be paid.

Nearly half the 140-day session was devoted to the $1.3 billion school finance reform plan ordered by the Texas Supreme Court and passed Monday. The new plan will significantly change the way public schools are funded in an effort to end the wide disparities between rich and poor districts.
