More practice with mathematics at UniWatch
Outside of those options, depending on exactly what you want more practice problems for Schaum's Outlines are great for that as they have tons of problems, including asnwers and fully worked problems. There's a Schaum's Outline for just about everything; if you're doing Physics or Engineering (any discipline) the Schaum's Outline of Advanced Mathematics for Scientists and Engineers will include just about anything you might get over the length of your degree, unless you take some optional modules in PDEs or something in 3rd/4th year.
Bear in mind any problems you find or whatever won't be tailored specifically to your course (unless your current lecturer wrote those maybe while teaching a similar course at another uni - which does sometimes happen serendipitously) so you'll need to use some initiative to identify which are relevant for your course and at the right level to be useful.
I am studying mathematics at university. When I learn something, I complete the homework set by the lecturers. This helps me practice what I have learnt during the lecture. However, I still want more practice. Does anybody know any websites that will let me practice more questions on an university level that will help me apply what I have learnt in my lectures?
