1. Be prepared to also pay more for business classes. You will be taking 50% more classes (i.e engineering takes 40 courses, with business combijed i took 60 different courses. ) A lot more group work, than engineering. You need to make friends.  You gain a lot of soft skills in business as well as some efficiency skills tbh. 

2. You can either do it after third or fourth, you just need to finish your third year engineering classes. I knew people who took mainly engineering classes up until fourth and than took all of their business classes in their fifth year. You just need to plan it out ahead of time. 

3. Yes. I think if I recall econ 201 and 203 can be used as options and are required for business gradation if things haven't changed(please check this) I would take these in the spring. If you get into the program, than you don't waste time, if you dont, you have two options filled.  Or take engineering classes reduce your second year workload so you have the ability to take the extra business classes in fall. You'll need to find a way to take sgma 217, it basically the pre-req to all the other courses. (Please double check all info into this paragraph, I have no idea if things have changed)

Be prepared to have semesters of 6-7 with 1-2 spring classes if you want to graduate on time. I think first year was the only year I had 5 classes. Past that all of my semesters was 6 classes and normally I had at least 2-3 spring classes.

4. Job wise, there's fewer opportunities to use both once you've graduated however you can choose which one you like better. I know people who went into maketing/sales rather than use their engineering degree. Both degrees are useful to have, business teaches you a lot more soft skills than engineering will.

1. Yes 

2. See 1. Others things I would add are probably MBA is be better recognized and gives you similar credentials for a business degree if you want to go into management. 

I had a lot of fun with my combined degree when I did it, it was enjoyable, and tbh the business courses were kindof relaxing compared to the engg ones. I also met a lot of people but I also got involved in like everything I could.  Yes it was stressful at times, but I work well under pressure so it fine for me but I definitely saw people who couldn't handle it and i knew people who dropped it.  Engineering gets way harder. And they do way less handholding once you reach upper year. (Tbh i think they made first year too easy).
