its the introductory maths for engineers Higher National unit and covers complex numbers, basic calculus and integration and differentiation, which will all be needed when you do the parts of the course covering these other Units: AC Networks (complex numbers) | Analogue Electronic devices and Microelectronics (complex numbers and differentiation) | Operational Amplifiers (Complex numbers) and anything involving tuning circuits/filters and Oscillator circuits- Circuit resonance etc..... As part of the HNC/HND the unit you do after this is called Maths for Engineers, after that you can do another one called Maths for Engineers 2, which used to be called Calculus 1 for Engineers, this is for if you want extra points to go for an HNC with Merit (which is based on getting about 10% more points tallied up than the number needed to obtain an HNC certificate.....this only takes about 2 weeks extra if you keep your head down, and sometimes you can do it alongside the Maths for Engineers Unit, but you have to make it known at the start of the year you want to do the extra Unit (Maths for Engineers 2) or you will be made to do it at the end of the course or even come back for a few weeks at the start of next college year..... getting a Merit on an HNC is the difference between getting into the start of first year at University doing all the same stuff over again but worded in a little bit of a different way, with all the expense of an extra year of study for basically nothing extra learned, and getting into the start of year 2 of the same course....making a University course 2 years long instead of 3 years..... Doing an HND at College then going into 3rd year at University is actually much better as the College has the time to teach/show you more whereas the University only really has the time for very minimal 1 to 1 time and very very little workshop time, which you will need to learn for the world of work anyway, Universities like people with HND'S as they are easy for them to deal with and they only have to go through the motions for 1 year to get you out the other end as a Graduate, not 3 years.....and employers like college then University as opposed to direct University entry as they know that Colleges teach a lot more hands on practical and tricks of the trade than Universities.... Colleges do Night Classes a few nights a week on different subjects and will be doing them now, you should get onto their website and email them or phone them asap...
