Hi
I am reading refrigeration and air conditioning 7th edit ion and doing a lot of Internet search . I m at a point that I am getting confused now. Please help me what should I do to pass 313 d exam now .
Thanks
Should I practice these tests foe days before test or if I pay now then i can access at anytime? I m asking because if u add more questions or change in future before i write the exam and I don't have access then i might miss all those additions
Thanks
