    Abstract: Biodiesel is a promising alternative fuel and has gained significant attention due to the predicted depletion of conventional fossil fuels and environmental concerns. This study aims to produce biodiesel from ogbono seed oil (using 98 ml methanol and 2g potassium hydroxide (KOH) as a catalyst) via transesterification process and to determine the physiochemical properties of the biodiesel produced. The physiochemical properties of the feedstock (extracted ogbono seed oil) were also determined before the transesterification process. The physiochemical properties of the produced biodiesel showed that it has a density of 0.5±0.00 g/cm3, pour point of 2.0±0, saponification value of 58.90±0.06 mg KOH/g, ester value of 98.0±0.5% (m/m), iodine value of 26.64±0.15gI2/100g, acid value of 0.28±0.05 mgKOH/g, moisture value of 0.0006 ±0.0% and trace amounts of ash content. The results of the physiochemical properties of the produced biodiesel agree with ASTM-D6751 and EN 14214 standard. Thus, it was concluded that ogbono seed oil is an excellent feedstock for biodiesel production via base catalyzed transesterification process

    Abstract: The study aims to evaluating the impact of guidance and counseling services on the academic performance of students in some selected secondary schools in Sokoto metropolis. Causal-comparative (Ex-post facto) research design was adopted for this study. This study involves a total of 200 subjects comprising 5 principals, 25 class teachers, 10 teacher counselors, and 160 students from the five selected schools. Data were collected using the four sets of questionnaires. Data analysis was done using descriptive and inferential statistics. The finding revealed that eighty percent (80%) of the students responded that their academic performance was changed after receiving counseling services. Seventy-two percent (72%) of the class teachers perceived the level of students’ academic performance after counseling as good, while 20% perceived it very good and 8% rated it bad. Guidance and counseling services have positively influenced the academic performance of the students and should be strengthened to improve the students’ performance in national examinations.
