Two great universities Lead the UK league tables Head international research tables Multidisciplinary – both arts in addition to sciences Include both colleges in addition to university Research Assessment Ox as long as d in addition to Cambridge are two of the top CS departments as long as research the following grades are taken from the five-yearly Research Assessment Exercises (1996,2001 & 2008) which are graded: 1 2 3a 3b 4 5 5 Cambridge scored the best possible: 5, 5 in addition to 3.35 GPA Highest ranking in 2008 assessment Ox as long as d scored 5 & 5 in addition to 3.15 GPA Overall 3rd in research power Teaching assessment There are many good Computer Science teaching departments in the UK: Cambridge, Edinburgh, Exeter, Glasgow, Imperial, Kent, Manchester, Ox as long as d, Southampton, Swansea, Warwick, York all scored 23/24 in the government’s Teaching Quality Assessment all rated above 80% by the Guardian University Guide 2002 do you trust either of these measures you need to check what they have in their syllabus is it good Computer Science is it what you want to do

Teaching: our aims To give our students an underst in addition to ing of fundamental principles that will outlast today’s technology To produce graduates who will lead development not merely cope with it Cambridge History Mathematical Lab founded 1937 EDSAC May 1949 Practical computer 650 instructions/s 1k x 17 bits paper tape input teletype output 4m x 3m 3000 valves 12kW William Gates Building

Some questions in CS Which algorithm is best as long as the job (cont) as long as a list with N entries method 1 (scanning) takes N/2 comparisons on average method 2 (divide & conquer) takes log2N comparisons on average comparison Some questions in CS How do I construct a secure automatic teller machine network how do I ensure secure communications between cash machines in addition to central bank database how do I recover if the central bank database loses its electricity supply how did the card + PIN system develop why not some other system how do I make it secure human factors impact on technological factors can I build a system which will be secure against a single corrupt employee can I build a system which will be secure against laziness in addition to stupidity Some questions in CS How do I model 3D shapes efficiently Bezier surfaces (1960s) NURBS surfaces (1970s) subdivision surfaces (1990s) How do I make realistic pictures from my database of 3D shapes ray tracing can be “photorealistic” polygon scan conversion used by all graphics cards

Computer Science Cambridge Course CS CS Ma Opt Computer Science Computer Science Year 1 Year 3 Year 2 Three years 1st year ½ CS, ¼ Maths, ¼ option from elsewhere 2nd, 3rd years 100% CS Select most 2nd year courses, half the 3rd year 100 students per year plus 40 part-time in 1st year General principles not vocational training Self-contained Draws on many disciplines First year choices Year 3 Year 2 Year 1 Computer Science Computer Science Computer Science with Physics, Chemistry, Geology, Physiology, Evolution Course components 8+8+4 = 20 weeks teaching per year 12 one-hour lectures per (6-day) week plus similar time in review in addition to private study 6 hours of practical work 2 or 3 supervisions of one hour each plus 4 hours of preparation each

Other A-levels A Physical Science is desirable Computing A-levels Computer Science good, similar in character to university-level CS but very few schools offer it ICT, In as long as mation Technology, quite different from university-level Computer Science not relevant Other subjects up to you e.g. history, languages, etc traditional academic subjects best Who should apply If you meet the prerequisites you’re excited about cutting-edge Computer Science (interest in addition to enthusiasm ) Then you must apply to Ox as long as d or Cambridge!
