Narrative:
ATIS reported ILS runway 25L and ILS runway 24R. We prepared for both. After being cleared for ILS runway 25L and at 9000 ft, socal changed the approach to ILS runway 25R. This was not just a sidestep, but an ILS with altitude restrs. I altered my heading to intercept runway 25R. By the time we had it tuned and idented and checked altitudes, I was north of runway 25R localizer. We both realized it at the same time, and as I began a left turn to intercept, approach called and said we were north of course and assigned heading 220 degrees to intercept. I believe our performance degraded by the fact we were rushed into preparing for a different approach at the last min. Lax tower and socal seem to be juggling aircraft at certain times. Previously, I have been cleared to land on 3 different runways.

Title: LGT ARRIVING LAX WITH LAST MIN APCH AND RWY CHANGES DEVIATES N OF FINAL APCH WHILE SORTING OUT THE LATEST CLRNC.
Narrative: ATIS RPTED ILS RWY 25L AND ILS RWY 24R. WE PREPARED FOR BOTH. AFTER BEING CLRED FOR ILS RWY 25L AND AT 9000 FT, SOCAL CHANGED THE APCH TO ILS RWY 25R. THIS WAS NOT JUST A SIDESTEP, BUT AN ILS WITH ALT RESTRS. I ALTERED MY HDG TO INTERCEPT RWY 25R. BY THE TIME WE HAD IT TUNED AND IDENTED AND CHKED ALTS, I WAS N OF RWY 25R LOC. WE BOTH REALIZED IT AT THE SAME TIME, AND AS I BEGAN A L TURN TO INTERCEPT, APCH CALLED AND SAID WE WERE N OF COURSE AND ASSIGNED HDG 220 DEGS TO INTERCEPT. I BELIEVE OUR PERFORMANCE DEGRADED BY THE FACT WE WERE RUSHED INTO PREPARING FOR A DIFFERENT APCH AT THE LAST MIN. LAX TWR AND SOCAL SEEM TO BE JUGGLING ACFT AT CERTAIN TIMES. PREVIOUSLY, I HAVE BEEN CLRED TO LAND ON 3 DIFFERENT RWYS.
