    Ahead of 2017 Unified Tertiary Matriculation Examination, UTME, the Joint Admissions and Matriculation Board, JAMB, has agreed on a harmonised timetable with other examination bodies in the country to have a hitch free examination.

    The Board at a brainstorming meeting with National Examination Council, NECO, West African Examination Council, WAEC, and National Business and Technical Examination, NABTEB, held at the national headquarters of the Board in Abuja unanimously agreed to harmonize the examination timetable because of the candidates’ desire for qualitative tertiary education.

    The harmonised examination timetable has put to rest problems arising from overlapping of examination dates, which would have disenfranchised a sizeable number of candidates.

    At the end of the brainstorming session, the bodies resolved that WAEC would speak to all its authorities that from 2018, between March and April, a window of two weeks be created where all other examinations that have nothing to do with Nigeria will be held so as to allow a window for JAMB to conduct its examination.

    The bodies agreed that for the purpose of the 2017 UTME, JAMB will shift its examinations to allow students face WAEC, NECO and NABTEB. However, a ten-day window for JAMB’S UTME has been created by all examination bodies for JAMB to conduct it’s examination.

    In view of this, JAMB will soon announce the commencement of sale of the 2017/2018 admission forms for UTME and Direct Entry, DE. JAMB emphasises the fact that whoever is presently collecting any money in the name of JAMB form should be reported to the Police or any other security agency as fraudster.

    NECO and NABTEB have also adjusted their examination timetables to avoid overlap in subjects that are common to the two examination bodies. A committee was set up to critically appraise the mandates of WAEC, NECO and NABTEB, the three examination bodies to make sure that each body sticks to their original mandate and with the possibility of working together in a synergy that they lead to collaborative examination for the purpose of students having results at one sitting rather than separate sittings.

    The essence of the meeting is to continually find solutions to challenges faced by candidates in the cause of their desire for tertiary education. Again, the Board is using this opportunity to inform Nigerians that it has not commenced the sales of its application documents.

    The forms will be out as soon as all critical planning are concluded to ensure a smooth examination in 2017.

    1a)
    A legume is a plant or its fruit or seed in the family Fabaceae. Legumes are grown agriculturally, primarily for their grain seed called pulse, for livestock forage and silage, and as soil-enhancing green manure.
    1b)
    i) Dry beans ( Phaseolus spp. including several species now in Vigna ) :
    E.g.
    -Kidney bean , navy bean , pinto bean , haricot bean ( Phaseolus vulgaris)

    -Lima bean , butter bean ( Phaseolus lunatus )
    ii)Dry broad beans ( Vicia faba ) :
    E.g
    -Horse bean ( Vicia faba equina )
    -Broad bean ( Vicia faba )
    1d)
    i) 15 bean soup.
    ii)Baked beans.
    iii)Bandeja paisa.
    iv)Bap.

    =====
    PICK JUST 5
    2a)
    i) Long term storage of fresh produce (12 months+) without needing a refrigerator or freezer.

    ii) Environmentally friendly - using seasonally grown and locally sourced fresh produce, re-use preserving jars, reducing food packaging and reducing food miles.

    iii) Save money by buying in bulk and seasonally.

    iv) Flavour! Home canned food won't contain artificial preservatives, BPA or other artificial ingredients.

    v) Convenience - ready to serve in minutes.

    vi) Community involvement - both the canning process and sharing with family, friends and neighbours. Teach skills to the next generation.

    vii) Gifts - nothing beats a homemade jam for a present

    viii) Prepare for emergencies and/or illness.

    ix) Personal satisfaction. We love creating new flavour combinations that you cannot buy in your local store - and showing how to use canned food in cooking dishes (ie marmalade in a stir-fry)

    x) Learn more skills ie how to use all of the fruit and reducing food wastage. For example: apples - make apple slices (or pie filling), extract juice from the peels and cores.


    5ai)
    Recipe is a set of instructions for preparing a particular dish, including a list of the ingredients required.
    5aii)
    i) List of Ingredients
    ii) Amount of the Ingredients
    5b)
    i)Include a variety of foods from the major food groups:A balanced diet requires eating a variety of fruits, vegetables, whole grains, low-fat dairy products, and lean protein (this includes beans and other legumes, nuts and seeds).

    ii) Use a variety of ingredients, flavors and textures:Since calories, nutrients and fiber content of foods in the same food group can differ dramatically, good nutrition depends on getting a variety of different foods from within the food groups.

    iii)Take proper portion sizes into account:When people are faced with overly large portions, they tend to overeat. Check the packages of foods you’re preparing to about serving sizes and follow the guidelines. Unless you intend to make a lot of food so that there will be leftovers, try to follow basic serving size guidelines.
