Enter the room with a Missile selected on auto-cancel, holding angle-up. Fire a Missile shot to kill the first Skree, then run right and immediately fire a beam shot to destroy the shot block. Run off the edge and down-grab onto the next platform. Run and jump directly up where the shot block used to be, moving quickly enough to dodge the Skree projectiles by going under them. Use a wall jump, HiJump, or a mid-air spring ball jump to make it up.
