# How you should study to get AIR 1 in GATE Mathematics?

Engineering Mathematics, as a subject, is very much relevant to the GATE exam as the weight-age given to this subject has been consistent over the years in comparison to other subjects. Every year you can find the weight-age of this subject to be 8 to 10 marks.

Engineering Mathematics is a subject that has a very wide course as this course during the college days is covered in 4 to 5 semesters and to prepare it completely at one time is overwhelming. So the key to prepare for such subjects is to keep short notes handy with you or maybe you can have a sort of Formula Sheet so that you can look up to a concept whenever you need it.
