Block

At uni students have lectures and tutorials; sometimes because of being unable to make perfect classroom arrangements, students might have to have their tutorials another day. Are they correct English?

-It's better to have lecture and tutorial as a block.
-It's better to have lecture and tutorial consecutively.
-It's better to have lecture and tutorial in succession.

Because many students do not live on campus; if attendance is taken, many of them would have to travel long distances to attend a class that might simply be an hour long, such as a tutorial normally would take.

All correct, but I would use "It's better to block/group lecture and tutorial classes together."

Thank you~
