I just wanted to double check if u can have 2 labs that are EOW but on the same day and time. Like say a bio and a chem one. If the timetable organizer allows me does it just mean that one lab is one weak and the next lab is the weak after. I wonna make sure that this is possible and that there isn't any potential timetable conflict

It depends, some labs are one week and some labs are the other week. You won't know until you attend class though. But if it does conflict you can try and switch to the other lab that occurs on the other week.

I see I just wanted to make sure that the schedule helper online can recognizes what week those labs are and so if it clears the 2 with no conflict it is in fact because the system recognizes the alternating pattern of those 2 labs.

Not sure if the system knows that though... You can always try and if it conflicts don't save it.

This might work out initially, but the one thing you have to watch out for is what happens when the regular schedule is disrupted for some reason. For example, I know that last year, first year Chemistry had no labs during the week of Thanksgiving, but Biology did. If this happens again, your alternating labs would suddenly be at the same time, which would definitely be a problem! Also, first year bio has alternating labs and tutorials...so one week, you have a lab, and the next you have tutorial. Again, if you scheduled your chem lab for the same time, you'd have a problem!
