• Tumia miaka na majina pale unapoyakumbuka kwa uhakika.

Kabla ya kuingia kwenye mtihani: hakikisha una vifaa vinavyotakiwa, nenda kituoni mapema, usijadili uvumi wa maswali ya mtihani, na tuliza akili yako.

Kwa marejeo, unaweza kuangalia ukurasa rasmi wa NECTA wa CSEE na format rasmi ya Chemistry 032.

Nakutakia kila la heri katika mitihani yako ya Chemistry na History. Soma kwa utulivu, jibu kwa umakini na amini maandalizi yako.

Ushauri wangu wa mwisho: Usijaribu kusoma kila kitu kwa kina usiku huu. Imarisha mada unazozifahamu, fanya hesabu chache za Chemistry, kisha jibu maswali ya History kwa kujipima bila kuangalia notes.
