Yes!
Mine was about a 50 hour week for three years, and quite a few late nights brushing up my maths in the first year. Virtually everybody needs remedial maths - even those who (like me) had fairly recently left school/college with very good grades.
Not academic suicide - but it'll be a big challenge. Best of Luck.
If you want to be prepared for this, I'd suggest going to a good University bookshop (or Amazon) and buying a good "Engineering Mathematics" textbook and starting to work through it well before you start if you can. There are many, and most of them are good, but if you want a recommendation try
Engineering Mathematics, by Stroud , which I've personally found very good when brushing up on something important but rarely used like second order differential equations or complex integrals.
