Advice:
 Attend lectures
o The lecturer presents the most important material
o Your presence is strongly recommended
o Take notes and read them at home
o Keep them and review them later on
 Attend tutorials
o Read lecture notes and textbooks before tutorials
o Prepare questions and ask them
o Your presence is strongly recommended as you can
clarify some aspects not fully understood
 Do not miss any practical
o Practicals are compulsory
o You have an opportunity to exercise theoretical knowledge
 Buy the laboratory manual
o You need it during the lab sessions
o You can get it from Hodges & Figgis bookshop (campus)
o You also need a lab notebook

o Demonstrators – during lab sessions
 Work on your own
o Solve problems
o Save solutions
o Devise your own problems
o Try to solve them
o Practice as much as you can
 Prior knowledge
o Binary Arithmetic: 2’s comp Add/Sub
o Combinational Logic: logic gates, KM
