I want to help you guys avoid all the pain in the first year so you can easily get good grades.
Pay attention carefully, these are the steps to get good grades.
Practice maths LOADS of maths, even go to YouTube and learn about "Discrete Maths used in Computing" this will make Foundation Of Computing so much easier. Take A-levels maths and even further maths if possible and if you're doing BTEC and dont want to take maths just go on YouTube and do a few hours every day.
Take Computing in A-Levels as it covers most of the stuff that's in Computer Systems, if it's to late to take that course just learn about the architecture of an computer.
Lastly but not least DO SOME FKING PROGRAMMING!!
I can't stress this **** enough, me and some of my friends didn't do any programming at all and its getting kinda stressful (haha) but I was able to learn it quicker than some people so its fine.
But if you take atleast 5-6 months or even 1year+ to study programming you will have more time for other modules and you will easily get 70%+ on your exam.
Sorry for this little rant but to be honest I wish I had this guideline before entering University hopefully its helpful and if you have any more questions feel free to ask me.
Good luck people. (p.s my spelling is ****)
