Help from peers and friends is easily found, but it may not necessarily be the right kind of help especially if they are having just as hard of a time understanding finance as are you. Nonetheless, there are some expert sources you could turn to in times of need.
Your seniors in school or college have been through the same problems that you have, and they successfully passed the challenge. It would be helpful to approach someone among your seniors whom you know to be good at finance and who would be willing to help. Even if they have their own workload and may seem busy, there is no harm in asking them. More likely than not, they would be happy to help you with your homework as long as you approach them nicely.
Most teachers are very happy to help and even prefer that you come to them with your queries rather than botching your assignment completely. However, it would be wise that you went to them at the earliest possible time rather than the last possible second before submission. It is also advisable that you try and raise any questions and concerns during class so that they may be clarified there and then, rather than you carrying the confusion around for days after. No one is more of an expert on helping you with finance than your teacher, so raise your hand as often as you can.
Most universities have online podcasts of their classes for students to access, and these are also available for students from other universities to view as well. If you find that you have trouble understanding your professor, it might be worth a shot to test out some podcasts of other professors at your university or another. Listening to podcasts is like attending a class, but right in the comfort of your home. With so many options of professors to choose from, there is bound to be one that suits you perfectly.
There is no doubt that tackling a new subject can be difficult, but as long as you start in time and take steps to get the right help you need, there is no reason why you should not succeed in doing your homework successfully and with complete understanding of the subject.
