We will assist with 4-ish years, to allow for unusual circumstances. Both Ds are in engineering and had a lot of AP credit. They are both self-driven students and work closely with their advisors on schedule planning. They are at different universities.
D1 is graduating this month in only 3 years, with a BS in ChemE and a minor in Spanish. She crafted her 3-year plan with her advisor in her first semester and stuck to it. (She did “overload” by 1-2 credits several quarters with her advisor’s consent. We actually pushed her to look at lightening up a little!) She is staying her fourth year to get a MS but has fellowships and stipends to cover the majority of the cost. Most of her friends (almost all engineers) will graduate in four years with a handful graduating with her a year early.
D2 just finished her first year, pursuing double degrees (BS in engineering and BM in music performance). We agreed to help her with a fifth year if she sticks with both degrees and makes good progress. She is doing very well and, per the plan worked with her engineering and music advisors, may be able to graduate in 4.5 years. (Also overloading by 1-2 credits occasionally. Again, we are challenging to make sure she stays healthy and sane even if it means an extra semester.)
